Title: Acoustic multi effect
Post by: stevie1556 on October 20, 2018, 09:30:21 PM
I'm thinking of trying to build a little multi effect unit for my acoustic guitar. Mainly because I think it would be fun to use but also because I'm thinking of doing some open mic nights in the future.

I can't decide which circuits to use though, despite doing some research and watching videos on YouTube. At the moment, I'm thinking of compressor-chorus-delay-reverb.

Compressor - I've read that optical compressors sound nicer for acoustic, so would you use the 4:1 or the Afterlife and why?

Chorus - thinking of using the Glam, good idea?

Delay - Mimik or Cave Dweller? I built several of the original Cave Dwellers and loved the darker, maybe even eerily sound, but worried it may not suit the acoustic well for a nice sounding, ambient delay.

Reverb - thinking of the Ping, unless there is a better option.

Essentially, I want the controls to be simple as it needs to be a simple pedal. The compressor is going to be wired as always on I think, although I'm not sure how beneficial it may or may not be.

I'm also thinking about powering it with a power bank, I use a brilliant one for when I go away with work that has 20,000mAh, 5VDC and 3.4A output. Obviously I'd need to get that ramped up to 9V but I'm failing to find anything good online that could do that, as having a power supply indie the pedal could be quite cool, although I'm not sure how handy or beneficial it could be.

Sounds like a fun project.

I like the 4:1 and it is probably a good choice if you want simple and transparent.  It also has a clean blend for parallel compression, which seems to me to be a great idea with an acoustic guitar.  But...in the guitar pedal world opto comps do tend to be more transparent than other kinds that is not because optos can't be made on the radical side, or that a VCA or other type can't be made quieter or more transparent.  Something like Merlin Blencowe's Engineer's Thumb is a good example.  It's more tweakable than a 4:1 or a normal/Dynacomp style comp, but is quiet and fairly simple and may just the kind of thing you're looking for in your application.  But it doesn't have a clean blend.  But it's worth checking it out before you commit.

My vote would probably go to the darker delay because I find acoustics sound brittle with anything too bright, and a delay is already quite busy for an acoustic rather than an electric guitar.  So I'd go cave dweller on that front.

Also: not trying to threadjack, but your post reminded me of something I saw at a music store last week.  It was a Yamaha acoustic-electric with a built in effects module.  Okay.  Nothing particularly special or exciting so far.  But the way it went about the effects were unlike anything I'd ever seen before.  The guitar didn't need a conventional amp.  Near as I could tell, it used a (fairly large) resonator disk attached to the back of the guitar from inside the body cavity of the instrument.  There was a 9V battery which powered both an effects unit and I assume the electromagnets to make the disk vibrate.  So you could get chorus and reverb to come out of the guitar while playing without an amp.  From a technological POV it was really cool.  From a practical/sonic perspective, it sounded like #@$!.  Just awful.  AWFUL.  The cheesiest worst stereotypical 80s sounds you've ever heard.  But from a technological perspective, it was kind of awesome.

+1 on the 4:1 it's one of the few pedals that never leaves my board.  I'd add a Sonic Maximizer of some flavor.  It's an extremely subtle effect but can rip sounds out of an acoustic you might not know are there.  Especially in the top end.  Only problem I had was the guitar was sometimes prone to "handling" noise, you could hear your shirt brushing against the back.

My buddy swiped my Mimic the first time he heard it and uses it mostly with acoustic.  I'm more of a fan of pristine digital delay and reverb so the new FV-1 projects here would be worth looking into.  There's no shortage at PedalPCB as well.  A chorus is a nice effect to fatten up a passage, especially if you're playing solo.  It gets old quickly but can punch up parts that benefit from a doubling sound.  The Glam has a noticeable delay which may, or may not, be to your liking.  The Pork Barrel might be a bit more lush sounding.

Lastly, a boost is nice to have for when you need a solo or single note lines to pop.  No shortage of those...

+1 to the FV-1 - that is a great suggestion.  You should look at the FV-1 projects on PedalPCB.  You could make a custom EPROM with several kinds of delay (clean, analog, etc) as well as the basic modulation effects you want like chorus and reverb.  I have not heard the chorus, but the delays and reverbs are excellent.

Thanks for the reply guys.

With regards to the FV-1 boards, I've had a look at them but I now have many more questions then answers in my head about them, but that's going to be for a different thread.

I'm also after simple, and cheap effects. The main reasons being that it's more of a test pedal, it's going to be taken to open mic night gigs if I ever get brave enough, and my guitar teacher friend has a lot of students who are starting to do open mic nights and want to help boost the stage presence of their acoustic guitar. Plan is for them to use mine, but if they really want one for themselves then it wouldn't cost a fortune to build them one.

So I'm thinking the 4:1, Glam, Mimik, Ping and a boost of some kind. What boost to use, I don't know yet.

Ahiddentableau - that guitar sounds like a fantastic idea on paper, maybe not so much in practice though. Wondering if it could be done better and on a cheap budget, maybe if I get a cheap guitar I can try it! As for the delay, I've got an SMD 1590A version of the original Cave Dweller although I'm not sure if the boards will work or not, plus the board mounted pots of the G builds, and the pots all being lined up with the same spacing is a rather attractive option.

Gordo - I've looked at YouTube videos of a Sonic Maximiser, definitely interesting although I'm not so sure about using one. Also the fact I'm thinking of using a 1032L enclosure, I haven't seen one in quite a few years (I powder coated some for a friend who was doing a multi effect pedal), but I think the max foot switches to fit comfortably is 5 (Although I could be massively wrong, quite likely that I'm wrong).

Please don't misunderstand me: I am not endorsing that guitar or its technology in any way.  It was the most horrible sounding thing I've heard in ages.  The worst.  But the idea was clever as hell.  I know I never would have thought of applying chorus or delay acoustically.  Then again, why would you when pedals do it so easily and so well?  If you're going to use a PA, then building a pedal of the type you've got in mind makes a whole lot of sense to me.

I've pulled the trigger and ordered 4:1, Glam, Mimik and Ping. Decided to treat myself and order a few of the Dreamtime boards as well as I know at least one friend would love one (and I'd love to try it out!).

I've got a board for a booster already, just need to check to make sure that it works.

Now to spend a small fortune ordering the parts for everything. I'll update with the progress on this. Thinking of powder coating the enclosure, using a laser water slide decal then a clear powder coat on top, which works fine but need to make sure there isn't any water marks left over otherwise they will show up. No idea what colour would be cool for it though, maybe lime green with sparkles in it?

Would I be right in saying the signal chain needs to be compressor - boost - chorus- delay - reverb?

I'm crap at coming up with pedal names so any suggestions is greatly appreciated :)

Comp first, reverb last, yes.  But I think different people could give different answers about the order of delay and chorus (which is probably the best possible way to say that it doesn't matter much).  The old school way would be delay before chorus, but the modern consensus seems to be "modulation" effects before "time" effects, so the order you gave should be just fine.

Post some pics when you build it.  I'm sure I'm not the only person around here who'd be interested to see it.
Title: Re: Acoustic multi effect
Post by: stevie1556 on October 30, 2018, 10:11:18 PM
That's my issue, everyone has their way of ordering pedals so it's just a case of finding what I think is best. But while I'm waiting for all the parts and PCBs to arrive I was going to start working on the enclosure, which I now can't do.

Don't worry though, I'll be posting progress updates. I'm hoping it goes quite smoothly as I'm already currently having issues with my Big Muff boards. Need to try and find some time to play around with it more.  Got a lot of other boards that I haven't had time to verify either unfortunately.

Little update, all the parts and enclosure have arrived! The parts arrived a couple of days ago and turned up much quicker then normal. Got a 1032L enclosure from Das Musikding, and now worried that it's not going to fit with enough room between the knobs and foot switches. This leaves me with three options:

Option one - board mount the pots and mount them as high up the top side of the enclosure as the PCB allows and hope there is enough room to use the foot switch without stamping on the pots/knobs.

Option two - board mount the pots and have them on the long side of the enclosure with the foot switches on top. Issue here is that it will then be harder to change the setting on the effects.

Option three - mount the pots as high up as possible on the top side of the enclosure (maybe even in single file) with the boards mounted seperately to the long side of the enclosure.

Option 3 I think Is the safest bet, but I can't find any mounts to hold the boards in place. I found some on GuitarPCB but they are sold out and he doesn't ship those mounts to the UK, so if anyone has any suggestions on where to get some that would be great. I've spent ages searching, used different search terms, etc, and still coming up blank. I've included a picture below of what I'm after.(https://uploads.tapatalk-cdn.com/20181109/33e298b23a2061bfb17657162db32551.jpg)

I got some of those from Barry a while back but never ended up using them. I should still have them somewhere. You said your in the UK right? Maybe if I find them we can do a trade or something?

Ironically I have thought about an acoustic multi build myself. If I ever find the time I might make it happen. Although my original plans seem a little overly ambitious looking back. I was hoping for a 4:1 or Afterlife, a Ping, a Bloviator, a Cave Dweller, some type of tuner out and balance line drive. Something like that anyway. Time will tell.

I have a stand alone 4:1 compressor and it woks well. I have used it on bass and guitar. A nice circuit.

I've made a number of multi effect builds and these are my thoughts:

Out of the number of choruses I've built, I keep coming back to the Pork Barrel.  Yes, it's more complex and pricier, but it does sound better than the Glam or Little Angel imo, although both are pretty good, and I probably prefer the LA to the Glam.

I've used the Mimik a number of times, and it's a nice meat and potatoes delay - nothing fancy.  I've had no luck with the Cavedweller on pcb or vero.  Maybe I have a couple of dud PT chips, but the PT worked fine in the Mimik.  My personal favourite PT based delay is the Sea Urchin/Deep Blue Delay, but again, it's a bigger build.

Definitely get a Bloviator.  Mine stays on at the end of my chain (pre cabsim though).

A nice simple reverb is the original one knob Rub-a-dub, and the Equinox II was a good, if larger build.

The Afterlife works well, and I'm looking a 4:1 for when I update my Random Stranger build.

The FV-1 stuff does sound pretty good, but I think a lot of the wackier programs (Glimmer, Hypernova, Kaleidoscope, et al) out there sound a bit tinny to my ear and are a bit gimmicky imo, but that's symptomatic of multieffects in general.  The basic effects are pretty good, if thin imo, although I don't think the chorus in mine holds up to the Pork Barrel.

The thing with a multi is that, unfortunately, PCB size is an issue and when you use a larger pcb, it can mean you need a smaller one elsewhere.  There are larger than DD enclosures though (but I'm not a fan of their proportions).

BryGuy - many thanks for that, can't tell you how grateful I am there! I've done some measuring and I'm 99.9% sure that I can't have the boards with board mounted pots because there won't be enough room between the foot switch and the knobs. That means I either have the boards mounted to the back of the enclosure using those mounts, or to buy a new enclosure. I've seen some on Das Musikding that will give me an extra 15mm on the width which would help, and with board mounted pots will be a lot neater wiring wise. Honestly can't decide on which would be best to do.

I think you should look into doing the multi effect though, and I can honestly say that I've never done so much planning for a pedal before!

Willybomb - thanks for your thoughts on the pedals. I did look at the Pork Barrel, but I ideally wanted simple and cheap circuits, and also if I did go for board mounted pots then if I use all 1590G boards all the pots will have the same spacing. If it wasn't for those two points then I would have definitely chosen the Pork Barrel.

As for the delay, the Deep Blue delay sounds amazing, definitely one of my favourites. I've just found a stash of the boards designed by AlanP that I got from another member before I had a break from building. However, the boards are for the 1590A so I can't use board mounted pots for it, and the reason why I went for the Mimik.

I've had a look on YouTube at the Bloviator, and although I like it I'm struggling to see anywhere I would or could use it.

For the reverb, the first one I built was a Rub-a-Dub, and I absolutely loved it until one of my friends decided he wanted it for his gigging board. Decided not to use it for this one though, not particular reason.

I've only just looked at the FV-1 builds and don't know enough about them yet to risk putting one into a multi effect. I've just ordered some of the Dreamtime delays though so I'll experiment with them.

If I do go the new enclosure route so I can have board mounted pots, I'm looking at one of these https://www.musikding.de/Looper-enclosure-30cm (https://www.musikding.de/Looper-enclosure-30cm) however, I'd prefer the 25cm one but it's out of stock, but the slightly bigger one will give a bit more room between the foot switches which would be nice. It's also 15mm wider to accommodate board mounted pots with a bit more room between the foot switches and knobs.

I was going to go the clickless route using the 1776 Finish Line, but I've worked out that it's going to add just over £50 to the cost of this build, and as it's already costing slightly more then what was ideal I'm going to stick to the 3PDT route.

I, too, have the PCB holders from Barry and like BryGuy haven't had occasion to use them yet.

I'm pretty sure you could get them at a DIY computer type place (or Mouser/Digikey/etc) if Barry is out of stock.

Another option is Sugru, www.sugru.com‎, which is kind of like mouldable silly-putty-glue that hardens (not rock-hard, it's rubbery). Jam some of the sugu putty where you want to place the board and squish the board in place. My sister-in-law gave me some, highly useful stuff.

I've also experimented with pizza-box topper-stoppers... the plastic 3-legged (usually 3) little dollhouse tables pizzerias use to stop the box-top from caving in on the pizza. I snip off the legs and then use hot glue to mount the little legless disc to the enclosure. Short prevention barrier and mounting point all in one.

Another barrier with hot-glue is the plastic pull tabs from cartons of milk, essentially they're a smaller version of the pizza disc.

If it's not board mounted, I stick the vero/pcb to the enclosures or pots with double sided foam tape.

Small update - the boards have arrived, kinda. Unfortunately I got a card yesterday to say that they have been hit by customs. I tried to pay the fee online yesterday but they then can't delivery it until Tuesday, so I'll take a trip to the post office tomorrow to go pick it up.

Enclosure update - the new enclosure has arrived. I'm not entirely sure it will allow for board mounted pots, I'll wait until tomorrow to see (I was about to make some paper cut outs of the board sizes to measure up to the enclosure).

Willybomb, send me a PM with your address and I'll post one out to you!

The issue with finding those board holders here is that I can only think of one shop that would sell them but they went bust unfortunately. I was thinking about using those double sided sticky pads (generally use them in the 1590A builds), but I'm worried about the back of the board shorting out against the enclosure. That Sugro stuff, I remember reading about it several years ago and completely forgot about it, thanks for reminding me :)

Willybomb, I'll get the board in the post tomorrow for you!

I've finally had a spare bit of time today and done some playing around.

The boards look great, can't wait to get them all built up! If anyone wants the 3 SMD soldering test boards from the Dreamtime then give me a shout as I don't have any use for them.

There isn't anyway I can use board mounted pots in the 1032L enclosure. If the boards are mounted on their sides, they just about fit along the side of the enclosure (but then that could interfere with the pot placement, and placing them too close to the foot switches). So that leaves the looper enclosure. The bonus is that it's 5cm longer, which is a massive bonus for space, but there is a ridge that is used to secure the end plates that run the length of the enclosure that could get it the way, may need to use the Dremmel to trim that down. Its also quite tight in getting the board and foot switch mounted with enough space between them, so my measuring and drilling will need to be 100% perfect.(https://uploads.tapatalk-cdn.com/20181121/596817b1da9ce5c7f8672c5a8f95eaa3.jpg)(https://uploads.tapatalk-cdn.com/20181121/e4097d96fa6e65b1729b71cf8df1ce56.jpg)(https://uploads.tapatalk-cdn.com/20181121/47f2a6d023f5b31398f32f859d4034da.jpg)(https://uploads.tapatalk-cdn.com/20181121/171a93590a8a84b72a1dcdd4c123cdb5.jpg)(https://uploads.tapatalk-cdn.com/20181121/0cde073fb196b076c2e57c4fe234124c.jpg)(https://uploads.tapatalk-cdn.com/20181121/9d108f6c43caead78e11eef2be47180c.jpg)

Got my first bit of work done on the boards today! Got all the resistors, diodes and ceramic capacitors fitted, apart from one ceramic capacitor as I can't seem to find that value in the components that I ordered.  Genuinely forgot how much fun building a pedal is when you're not building for someone else, I can't even remember the last time I built one for myself.

Unfortunately work is going to get in the way of doing some more soldering on them tomorrow, so hoping to get all the capacitors soldered on Saturday if work decide not to call me in, otherwise they will have to wait until Monday.

So, what enclosure are you going with?  I'd love to build a flyrig of some sort, but the looper enclosures aren't deep enough for my liking.  I've looked (briefly, shallowly) at cable channel, but what's stuff you've got in the last photo?

The 1032L was my first choice, as it's diecast aluminium and the type of enclosure that I'm used to, but the boards didn't really fit inside it. So I've gone for a aluminium looper enclosure. Its slightly shallower, I've just put them side by side, and probably only about 7 or 8mm shallower at a rough guess. The big advantage is that the looper enclosure ends come off and the bottom panel slides off, and with it being 15mm wider, it provides a lot more space inside it.

Here is a link to the one that I've ordered https://www.musikding.de/Looper-enclosure-30cm (https://www.musikding.de/Looper-enclosure-30cm)

I did also get the miniature electro capacitors for it just in case, but even with normal size ones they would fit easily.

Little update, today has been rather productive, managed to get to the cinema before my on call time with work started, had lunch with my friend as well. Still hadn't been called to go into work by the time i got home so I managed to solder up the remaining parts on the boards! Managed to miss 5 capacitors on the part orders that I did so just ordered them and will solder them when they arrive.

Below is a picture of the (nearly completed) builds. A few other boards of what I've been slowly working on as well. One of the white boards is fully built but I'm currently trying to troubleshoot it.

Going to start working on the label design for it in the next few days. Is starting to come together quite quickly considering how slow all my other builds go. (https://uploads.tapatalk-cdn.com/20181124/77744322d2ae716c065c765fcd01f299.jpg)

You saying that has made me feel a little bit better about it now!

Ordered some bits from Tayda, ordered the other bits from Small Bear for the multi effect. While doing that I forgot to order the parts for the 3 Dreamtime boards that I got so I had to places a 2nd order at Small Bear for those parts, then had to place a 3rd order with them for the jacks! Thankfully they noticed what I did with the jacks, bundled them into the 2nd package and gave me a $16 refund on the postage. I was wondering why I had a refund from them until the package turned up. I swear on these 2 builds I've spent more okkn postage then on components!

The Musikding enclosure is a cable channel by a company called Rose & Krieger. I mailed the distributor in the US, if they deliver small cut offs (e.g. 60 cm), but no reply so far.

Any other source in the US for something comparable would be great (as I am re-designing my Linda Looper and could share it with the US guys...)

Marshall Arts - if it helps, I don't mind posting one to you if you can't find an alternative (you should be able to though). Only thing is, it wouldn't be cheap on the postage I imagine. It was €9 euros postage to ship each enclosure to the UK from them.

Little update, the missing parts have arrived! However, I've found the ceramic cap that I was missing in one of my component bags, so I'm guessing I've got the film caps someone as well maybe.

Question for the people that use acoustic boards, is it worth incorporating a switchable buffer into it? Only reason I ask is a couple of years ago I designed a buffer using Beans Cornholio schematic, and made the mistake of ordering the boards after being up for work at 4am for 5 days in a row and ended up ordering 200 of them. I'm sure you can imagine that I have more then a few boards spare!

Sorry, didn't mean to hijack this thread. I was thinking of the guys in the US... I live in Germany, so I don't have problems ordering the enclosure myself.

On the buffer question. Yes, almost always better :-)

No worries about that. I think it was good as finding decent looper style closures is hard, especially in the UK, and if it benefits others it's always worth sharing :)

I'm thinking about putting the buffer on a switch just in case it's not wanted sometimes (my guitar teaching friend does a lot of acoustic work).

Going to start working in the enclosure in the next few days, doing the label and drilling template, depending how long that takes, I maybe able to get the enclosure powder coated on Tuesday, otherwise it's going to have to wait until the following week.

Haven't been able to do much on this as I've had a bad case of man flu. But today I'm feeling a bit better so I've pulled my finger out and done a bit of work on this.

I've got my label designs done and marked the lines on the enclosure where I want the foot switch and top row of pots. I haven't got any transparency sheets here but I've got those A4 paper pouches for folders. Stuck the printout of the labels into one of them and marked out the drill points with a pen. It worked well, but the gap between the top pots and foot switch is a few mm too far apart. I'm going to adjust that in a bit and print it out so I can mark the drilling points.

I'm hoping writing this here will give me the motivation to get it all done, so today I'm planning on redoing the labels, marking out the new drill points on a plastic sheet and then transferring that to the enclosure. With this, I've also got to work out the spacing between each effect. This is providing work don't call me to go in. During the week I want to get the enclosure drilled, get to the print shop to get this new no film decal sheet printed on, then at the weekend I'm planning on getting round to my dad's to paint the enclosure and get it labelled up.

For lining up the labels, the plan is to drill the pilot holes at 3mm, then use the circles on the decals to line them up directly over the holes.

For the colour, I've got a lime green paint with sparkle bits in it. It's a bit bright, but I think it will really make it stand out.(https://uploads.tapatalk-cdn.com/20181217/76a327d63415a1feec77bf24bb540889.jpg)(https://uploads.tapatalk-cdn.com/20181217/dcd1e6120d2c103f7ba881e91bfb37a5.jpg)(https://uploads.tapatalk-cdn.com/20181217/895c5967e7000ec105c308f5a4129ede.jpg)

Made some more progress, although I realised another slight error that I made. I know the Ping reverb board is a different shape to the other boards and doesn't have board mounted pots. The thing I didn't notice was the pot controls are an extra 4mm wider then the other boards.

Ideally I wanted the pots to all be evenly spaced on the effects so I didn't want to move the pots and labels for them (I know it's 4mm and I'm being a bit OTT on it). I can't mount the board onto the pots anyway so I decided to keep the pots and labels spaced the same as the other effects. If I've worked it out right, I should be able to mount the board the to enclosure between the foot switch and the pots and have about 2mm spare.

I've managed to adjust the labels slightly, have to move the effect name, graphic and foot switch drill point up by 1.5mm. Normally I wouldn't have bothered, but there is a ridge inside the enclosure that's already making it pretty tight to get the foot switches in the right place, and I really don't want to have to be going at it with the Dremmel.

On the plus side, I've used the centre punch and marked out all the drill holes so I'll get the enclosure drilled with the pilot holes before work in a couple of days.

Using the plastic paper pocket for folder things worked well in principle, but they were too flimsy. While I've been sitting here writing this, I remembered that I've got the overhead projector transparancy sheets in my parents garage, I should have gone round there and used them as they would have been perfect for this.(https://uploads.tapatalk-cdn.com/20181217/fceb3ebbef0452ba4a71068bab341c49.jpg)

Got the labels printed out today! I've got 2 of each printed out so if I make a mistake then I should be fine.

I've put a more detailed post in the decal thread that I started, and although they couldn't use the PDF files, they could photocopy the ones that I printed at home. It does look like they have good ink coverage, although I'd have preferred it they could have used the PDF files.

The enclosure will be drilled tomorrow, going to get it painted as well, but that depends on a few other things and the amount of time I'll have. Labels will follow shortly after.

I've managed to get over to my mum's house today to drill a bunch of 1590A enclosures and the multi effect enclosure. I was worried about it being hard to drill, but I used the drill press on a low speed and it went straight through it.

I'm going to get it painted up tomorrow when I goto my dad's as all my powder coating gear is in his barn. It's going to be bloody freezing so I'm not looking forward to it. I'm not sure how long it's going to need in the oven, 1590A enclosures I normally do for 25 minutes with 4 at a time. I'm guessing maybe 30-35 minutes due to the larger surface area. I can't decide which blue colour to use though, here is the 2 colours that I'm thinking of.

I seem to be missing one of my Dreamtime enclosures as I marked up 3 of them but only had 2 to drill. Really not sure where it could have gone to.

Update, found the missing box hiding under my coffee table! When I was marking the drill points and using the centre punch I was watching TV.
