Title: Your suggestions on overdrives for mbp
Post by: madbean on June 02, 2019, 08:04:18 AM
The OD section of the Shop page is looking really pretty pathetic. I've spent a great deal of time working on modulation ideas over the last year and literally none on overdrive. What kind of OD projects would you like to see? I don't want to do clones of boutique stuff and there's already a lot of that out there anyway. Also, I'm not going to so anything that's already covered by the existing VFE projects since I still have lots of those boards.

More tube based projects, maybe? And different types of tubes? Or, something else? Something totally original (haha, yeah, whatever that would be)? Maybe combining OD with another type of effect...hmmm.

One project I do hope to add this summer is my (discrete) pedal version of the Vox Night Train, if I can finally get the damn thing to work right. Maybe a couple more amp to pedal conversions? I used to do one for the Carmen Ghia several years ago that was pretty neat.

Anyway, throw your ideas out if you have them.

ODs are hard in my opinion to make something that different.

Personally, I've been chasing higher gain stuff at the moment and am wrapping up a chunk chunk.

So maybe amp based stuff like that but with J201 getting hard to find, maybe with soemthing else? I thought I read somewhere that the latest ROG amp pedals had moved away from 201s to something else, but I didn't dig enough to find what.

Btw I've been on a modulation kick too so I've enjoyed the new projects!

How about an overdrive that is controlled by a sluggish envelope follower.  Basically, as you play harder, you slowly drive up the voltage on a cap from the envelope follower.  Once a threshold is reached, the overdrive kicks in.  As you start to play more gently, the cap slowly discharges, and the overdrive goes away. 

Essentially, the overdrive senses your mood.   ;)

I don't think there's a project for the EHX GermOD. I always thought it was a neat pedal, but it's not too terribly exciting. It had a voltage starve and no output volume control. It was actually my dirt pedal for a while.

And you're of course welcome to any of my projects that didn't get picked up by someone else. I think Thomas's Cruise Drive board is the only dirt pedal of mine besides the Snow Day out there. Like the Rust Bunny is a pretty rare bird with lots of room for modification.

One neat idea would be if you could give access to a digitally-controlled pedal that could switch numerous characteristics at once with a small rotary. This is something that's become a bit popular in boutique stuff but hasn't happened on the DIY end./\

More tube based projects, maybe? And different types of tubes?
Nu-tube would definitely be interesting

Something totally original (haha, yeah, whatever that would be)?
The key to the Klon's success seems to be doing different things with multiple paths... so maybe something that expands on that idea in a different way could be interesting. Just a thought, but are there any interesting studio mixer tricks that haven't shown up in pedal form yet?

Maybe a couple more amp to pedal conversions?
VFE/Peter had some RunOffGroove "Licensed" boards in the Standard VFE format at some point and they are not in the VFE board files bundle he is selling. I like the idea of being able to swap the guts/enclosure in a semi-modular way so It would be interesting to see if those could ever be made available again. He also had 5 or 6 BYOC adaptations.


These are the RunOffGroove ones I know about:

RunOffGroove 22/7 - CMOS implementation of the Big Muff Pi with a flexible tonestack

RunOffGroove Azabache - original overdrive inspired by classic Fender amps

RunOffGroove Britannia - original overdrive inspired by the Vox AC-30 Top Boost amp

RunOffGroove Eighteen - Marshall 18W adapted for use as a distortion stompbox

RunOffGroove Ginger -  Ampeg SB-12 Portaflex adapted for use as a bass guitar distortion stompbox

RunOffGroove Supreaux Deux - Supro 16T adapted for use as a distortion stompbox

RunOffGroove Thor - Marshall 100W Super Lead adapted for use as a distortion stompbox

RunOffGroove Tri-Vibe - versatile modulation effect that offers true vibrato

RunOffGroove Umble - distortion stompbox, inspired by Dumble amplifiers

RunOffGroove Uno - Boogie MkI adapted for use as a distortion stompbox


The VFE bundle also had some alternate switching boards in it that would be neat to use with these for something like a direct box, or mic effects.

Lots of od/distortions sounds the same... what i would love is a prunes and custard or animato type  of overdrive . Something with a envelope . Mayde like a modified mxr distortion II with 2 diffrent kind of distortion mix into one ^^

Something with a envelope .

The EHX Graphic Fuzz is a Muff Overdrive that has an expander in it which is pretty neat... You don't see that a lot.

with 2 diffrent kind of distortion mix into one
Isn't this what the VFE Dragon/DragonHound is... An AlphaDog and PaleHorse in one box.

I like this. Be it 'characteristics' or a full on switcher-o type thing where you can go through a few different classic overdrives. Between your shop and the others you have linked from the forum, I feel like there's access to nearly any type of drive someone could ask for, so offering something with a new function like this would be a step up vs. the one-sound or topography differences. Maybe something like a Select-a-amp pedal.

Or maybe pursuing the amp-type drive subcircuit without J201's, a broader project like the ROG's Fetzer Valve but with a different device that could trickle down to various circuits. Would be more a circuit snippit or subcircuit project that could trickle down to a multitude of circuits. Of course the Fetzer valve was built in part on a large amount of other people's research, so maybe that's asking the for the impossible.

I'd also be interested in drives that do the supro/LZ1 sound (the ones without the tonebender) or the balls to the wall champ sound from the Face's Stay With Me.

I'd really love a drive that does the clipping the focusrite scarlett series of USB sound cards do when you really push them.

Maybe some overdrive's with a clean blend/bass friendly designs. Something that cops the darkglass micro tubes or something. OD with 3 band eq with a switchable mid frequency center? Distortion with TMB tone controls where the bass is a tightness control pre-distortion that cuts bass, mids has a center control, and treble is ye standard treble cut.
Title: Re: Your suggestions on overdrives for mbp
Post by: benny_profane on June 02, 2019, 12:53:20 PM
I'm always interested in utility pedals that allow making existing things take on new flavors or roles in a signal chain. Specific to OD, that could mean switchable series designs or parallel options for gain. I know VFE has some parallel projects with frequency splits, but other parallel options with blend, etc. could be interesting.

Something totally original (haha, yeah, whatever that would be)? Maybe combining OD with another type of effect...hmmm.

What do you feel that's missing in the current market? What do you think is extremely tired (beyond clones, of course)? That would be the place to start when thinking about something original. You're very close to everything...with research, prototyping, auditioning...where's the gap?

Another thought is analog vs. digital. Do you want to wade further into digital stuff, or are we talking strictly analog?

Also, what were your thoughts in re combinations? Something like a drive and modulation might be too specific or only have a narrow niche, but an OD and amp emulation (with possibilities of swapping either stage) could be a way to integrate things and make a really full-featured gain unit.

How about an overdrive that is controlled by a sluggish envelope follower.  Basically, as you play harder, you slowly drive up the voltage on a cap from the envelope follower.  Once a threshold is reached, the overdrive kicks in.  As you start to play more gently, the cap slowly discharges, and the overdrive goes away. 

I think a responsive OD structured this way sounds interesting. What I like here is that it's thinking about a traditional effect in a new light...which is probably the key to moving forward.

So maybe amp based stuff like that but with J201 getting hard to find, maybe with soemthing else? I thought I read somewhere that the latest ROG amp pedals had moved away from 201s to something else, but I didn't dig enough to find what.

I don't necessarily think that moving away from J201's entirely needs to happen. Although, rethinking board layout to include SMD pads as well as through-hole pads for transistors might be the way forward. Coda Effects' Black Hole Sunn Model T board is an example of a project that incorporates this idea.

The amp projects overall I think are pretty cool. I'd certainly be interested in those.

Two of my favorite ODs were by you, just bring them back:
The Sparkplug 2 as perfect as it is.
And the Grease Gun tweaked out a bit with some more ... goodness. Broader Range, EQ ... idk.

Also, personally, I like two-in-ones: an OD with a boost or a treble boost or an EQ in front.
And amp-in-box pedals that work as the dirt channel on one-channel amps.
I know tho that all of this has been done by everyone.

Most of those are available by the usual PCB suppliers.
There is also the UBE Screamer, a Screamer based around logic chips.
That would be cool: amp emulators that need way fewer parts.

Title: Re: Your suggestions on overdrives for mbp
Post by: somnif on June 02, 2019, 03:04:11 PM
The problem with ODs is that they really are usually the most common and most abundant thing out there. Everyone and their uncle's uncle has a tubescreamer design, etc. Between Aion and Bugg there are a ton of "underrepresented" designs available too.

So, if you want to be unique, you may have to get weird with it. Or at least rare with it, so to speak.

Amp-in-a-box designs are always fun, though you may want to look at things other than the usual Vox/Marshall/Fender crowd. Sunn, Mesa, Dumble, aim for "Distinctive but under represented" (Granted this also could lead to "under selling")

Could also look at oddness or quirky. CMOS drivers, modulation, shove an envelope follower up its butt, something new and different. Gotta stand out some how, if you can. The Clari(not) has just about the simplest implementation of an envelope follower possible, and I've experimented with putting it all sorts of places it ought not be.... usually for good reason, its not exactly subtle.

Oh and yeah, we've reached an era where smd pads for JFETs is the way to go, unfortunately or not.

Post by: sonnyboy27 on June 02, 2019, 03:15:03 PM
I'd love to see a multi gain stage od (like a reduced gain version of the Friedman pedals) with a unique tone stack (3 band gyrator or baxandall). A cab sim would also be sweet as an add on for pedals like that.
Title: Re: Your suggestions on overdrives for mbp
Post by: marmora on June 02, 2019, 05:45:05 PM
I appreciate that OD designs are often what get people into pedal building.

I also appreciate the urge to reach out and keep pushing.
This might be more in the fuzz/distortion category, but I definitely like designs that use unusual parts. Anchovie's Noise Ensemble is a good example. No one expected a dirt/fuzz/mod pedal out of a PT2399.
I like set it and forget it, but I also really like pedals that use a momentary switch to punch in a different setting. Touch pads, external LDRs and other shenanigans are also welcome.
How this applies to ye olde dirt pedal is something I would have to give more thought to though.

As someone else mentioned, a blend control is also a welcome addition.

The Ibanez CR-5 Crunchy Rhythm. The schematic:  https://www.dirk-hendrik.com/ibanez_cr5.png (https://www.dirk-hendrik.com/ibanez_cr5.png)
As far as I can tell, nobody has made a pcb for this, and it's one of the most underrated overdrive pedals ever made. It's not another Tube Screamer, Klon, DOD 250; so that in itself is a breath of fresh air.

That's interesting.... Knowing Maxon, it's probably made from left over boards of another pedal in a different series, or at least very similar to one. They did alot of that... Who knows, it could be the elusive Ibanez SK10 Visual Super Product Sound From USA



Speaking of...This Reverb listing has a pretty good shot of the SK10 board and components:

I think that new and overdrive are two words that can't be in the same sentence  ;D

what about the sunn concert bass preamp?
Or a low voltage adaption of the sunn 2000s preamp.

A nice thing for overdrive (especially for bass) is to add a cap in series with the clipping section.
This is an example.

My bet is the SK10 is based on the (admittedly also obscure) FC10 Fat Cat Distortion (apparently the SK10 was made for a particular music company in Japan). Fun fact the "Visual Super Product" is the engrish translation of "Mirage"

Edit after snooping-
Hah, yeah, side-by-side of the FC-10 and SK-10 the boards look pretty much identical. Can't tell if all the component values are the same, but its gotta be close.

SK-10: https://i.imgur.com/OV1Tiq3.jpg (note it even says "FC-0101A" on the PCB, same as the fat cat)


In which case, yeah, its basically a Rat.

Include SMD pads for any jfets or other through holes that are OOP.

My idea is for a clean-blend Wyllie New Moon. The New Moon is a (switchable) octave fuzz where both the fuzz and the octave can have a swell/bloom effect like an envelope. With the clean blend it would be like having a fuzz-delay. Could be cool.

Yes, fuzz != od, but all od's seem about the same these days.

Btw... The LM7 LA Metal also uses the same PCB-FC-0101A board


Brian, (As DFX mentioned) How 'bout a JHS "Bonzai" style Ibanez SK10/FC10/LM7

The Maxon OD-01, which was likely the precursor to these, is very similar too(i think) but it is a different board (it has a OD/Distortion switch)

Iíve heard a lot of good things about the nobles odr1, though Iíve never looked at the schematic.

Iím with Mr Patton, some kind of digitally controlled multi component selection would be very cool.

But to be fair, once I built a Timmy I stopped building overdrives.
Title: Re: Your suggestions on overdrives for mbp
Post by: Aentons on June 03, 2019, 02:58:16 PM
Maybe combining OD with another type of effect...hmmm.

A couple more ideas are:

Pulse OD - an overdrive that modulates gain up/down and to compensate for the boost, also does volume down/up... like a tremolo but with drive instead of volume

Dirty Delay - combined delay into an overdrive
Title: Re: Your suggestions on overdrives for mbp

Post by: jjjimi84 on June 03, 2019, 06:22:34 PM
I would like an overdrive that makes me play better and gives me more hours in the day to practice.

But my ideal overdrive would be like thetimmy or vfe dragon, transparent but with flexible eq options but it would have second foot switch that would be able to toggle in whatever you set in the effects loop. That way instead of a dual pedal that is maybe just a od/boost or whatever, you could plop in a fuzz and delay.

Basically if a  klein bottle and a dragon had incestuous baby and left out a bunch of options, like only having one eye and nine toes.

Another idea... Sorry, please tell me to shut up if it gets to be too much. just brainstorming a little

We all know about tubes, diodes, etc.. Maybe try some unconventional ways to create mild distortion. We know that some of the best sounding stuff comes from being inefficient or sub-optimal.

... a couple of things that I have no idea about but kinda sound like it might do that.

- Overloading a thin wire, like a fuse

- underpowered or too distant Near field wireless induction. kinda like the wireless LEDs in the video from the other post, but with audio rather than power)

Well I wasn't expecting this strong of a response, haha. Good show!

Some really solid ideas in here - more tube stuff, amp ports, Grease Gun 2, old Maxon stuff, Sparkplug (that's already been completed but not released yet), and quite a few things I never thought of. Some suggestions might be a little out of my lane such as digital controlled analog overdrive, etc. Mostly I am looking for projects that will be fun, unique, and definitely not too time consuming to develop. And something high gain is well overdue as well.

Anyway, keep the suggestions coming. I think I'll make a spreadsheet of the suggestions and see how it could play out.

What I think would be exciting is a MBP 3-in-1 platform.


1790 box with 3 switches/effects with the option of independent switching or 1-of-3 switching, where the others turn off when you click one on.


Design the dirt PCBs to fit the platform perfectly with one 4-prong header to make swapping in and out new dirt circuits really simple.


Get PCB faceplates for each effect and include with the circuit PCB. This also allows for standard 6-hole control layout for each one, as the faceplate would cover any unused holes. You could even get Tayda/PPP to have the 1790s drilled and ready to go.

What I think would be exciting is a MBP 3-in-1 platform.

That's actually what I'm working on right now but I'm using a 1590dd since I'm using the VFE builds.  I doing a combo TS/Rat/BM and goanna build with headers for the internal connections and to the jacks and switchboard. That's the main reason I brought up the modular aspect of the "standard" VFE boards and maybe asking Peter about using his "standard" layout boards for the ROG preamp projects that I listed above.

I was actually planning on a sort of foldable mini-mega pedal by combining 2 to 6 of these on hinges side by side, and/or top and bottom


There is already a VFE switch board for the master switch idea as well. I think it's just for the double pedal tho

I was also about to post and ask if anyone had a drill template for the VFE triple pedal layout or the RUP, which I assume is the same

op amp only high gain ... for the absurdist angle, approach it like z.vex and just keep adding bacon bits boost stages until you get where you're going like he did with the SHO/SD2n1/BoR/BoM

The Ibanez CR-5 Crunchy Rhythm. The schematic:  https://www.dirk-hendrik.com/ibanez_cr5.png (https://www.dirk-hendrik.com/ibanez_cr5.png)
As far as I can tell, nobody has made a pcb for this, and it's one of the most underrated overdrive pedals ever made. It's not another Tube Screamer, Klon, DOD 250; so that in itself is a breath of fresh air.

I've got one of these coming... the proto board is here, just need some time to build it & write the docs!
Ah. This is music to my earlobes. I will definitely be down for ordering one of these when it's available.

I would think for different OD's, I would go more in the direction of super-OD's.  Something like the EQD Palisades, classic circuits with all the bells and whistles.

Storyboardist does a couple like that, his Bluesbreaker and Tube Screamer boards are very well equipped.

I have experimented with simple discrete op-amps for overdrives.  The result was my D-Tube overdrive (a discrete op-amp version of the tube screamer circuit), a layout for which I posted over at the Guitar FX Layouts site at the link below.  It works great and is fairly forgiving of the JFETs and BJTs used in the discrete op amps.  It also sounds a little different than an average tube screamer - perhaps a little smoother.

http://guitar-fx-layouts.42897.x6.nabble.com/D-Tube-A-Discrete-Op-Amp-Overdrive-tp41274.html

BTW, the discrete op amp topology I adopted is similar to that used in BOSS circuits like the Blues Driver.  However, I added a BJT buffer at the output of the JFET/PNP op amp part of the circuit.   I would think that you could apply this same discrete op amp idea to just about any one or two op amp overdrive or distortion circuit (Gainster, OCD, Zendrive, Klon...).  You could even experiment with creating a discrete op amp with an adapter that could be plugged into a 8 pin socket of an existing effect.  Lots of DIY fun!   ;D

I second the idea of thinking about enclosures as well as boards.  PedalPCB's having standard designs and then getting Tayda to sell predrilled enclosures is shockingly great.  You can do 'em up fancy if you like, but in general taking away one of the two most tedious parts of a build has made me want to build more than normal.  Doing faceplates is another great idea.

Digging up this thread again.

How about a version of the Blackout Effectors Mantra? Especially now that Blackout seems to be out of business.
Never seen a DIY version of this, although it was quite popular some years ago. It's a high gain overdrive with a lot of hair:

"Equally capable of invoking the sacred sounds of a classically refined overdrive AND summoning wickedly raunchy drive, with more crunch on tap than the overdrive moniker usually entails. With such a wide palette of tones and character the MANTRA will feel just as at home at the feet of the stalwart blues crowd as it will the quintessential rock & roll protagonists.
The MANTRA utilizes amp-like circuit architecture, with multiple cascaded MOSFET and JFET gain stages to insure the most natural, touch-sensitive overdrive conditions possible and a seemingly endless range of clean-up with your guitar"s volume knob. We burned a lot of midnight oil to make sure that the MANTRA could get down with vintage-type, low output single coils and hot humbucker pickups alike. From gently fingerpicked melodic phrases to bludgeoning riffs that you"ll want to play over and over and over..."

Schematic etc.: http://revolutiondeux.blogspot.com/2012/07/blackout-effectors-mantra-overdrive.html (http://revolutiondeux.blogspot.com/2012/07/blackout-effectors-mantra-overdrive.html)

There was a version available with a Low Gain Switch which bypassed a gain stage. I can't find a schematic for that though ....

I've been thinking about the possibility of an envelope controlled mux to route clipping paths or maybe tone circuits. Is this a possibility? It seems like it could be cool for really letting picking dynamics control the overall response of the pedal in a different way (at least not in one of which I'm aware).
Title: Re: Your suggestions on overdrives for mbp
Post by: Aleph Null on October 25, 2019, 12:41:37 PM
I'd love to see an overdrive/distortion that is an expander (that is, the opposite of a compressor) into a clipping stage. Exaggerating playing dynamics could make for a really interactive and touch sensitive overdrive.

I'd also like to see an implementation of the AMZ "warp control". Something that would let you blend between symmetrical and asymmetrical clipping.

The EHX Graphic Fuzz has an expander section. It's more of an od/dist than a fuzz.

Some of the VFE stuff has "warp" type blending controls. The Alpha Dog and Scream among others let you warp the clipping type

This is just to get the ball rolling. Re-designs of existing projects in line with my current layout style and a couple new/old ones. Not sure if i want to do the Lunchbox (BE-OD) since it's a bit out of character for me, but maybe.

These layouts are designed with options as far as enclosures - 1590B with regular bypass and side jacks (hopefully-it'll be a squeeze!), 1590B2 or 125B with top jacks and room for the Softie bypass.

I'll probably shoot for 5 or 6 more after I go over the responses in the thread again. See what I can cook up for the peoples.

The CFH is a very hacky effort. It's just a static SHO with clipping diodes and a tone control. But, it sounds quite good so I'm going to do a run of them. Also, CFH stands for Crotch Fire Hurricane.

I could do a Tonebender in 1590A. I'll work that up.

Wow. That was quick.

I was asking about the Tonebender because I recently built a 2-in-1, Silicon Fuzz Face & your Silicon Tonebender, which I had never built before for some reason. And I love it! A lot of fuzzes are useless on the first 75% of the gain range, but this is great all along, dirty overdrive to full on fuzz, and so simple to build.
Good to have the smaller version, too. Thanks!

Is that the mythical full blown Mysterioso Snr?

Indeed it is. Still one of my favorites. I have a version I built into a 1590B as an homage to the original but this one is 125B and a whole lot easier to build.

So, here's what I'm doing for sure:
- Grease Gun 2 (already know what I want to do with it).

- Rump Roast 2 (that's the Carmen Ghia I did a few years ago). I'm thinking the original in a 1590A and maybe a tube version in a 125B. Should it be a submini or 12ax7? It might be possible to set it up for either tube, actually.

- I really like he idea of the Graphic Fuzz but holey balls, it's pretty intense part-wise. Still, I may tackle it.

- I also really like the idea of a digitally-switched OD with different parts/values like the two JHS ones. I'd say that is a very high maybe.

- Still working on the Night Train OD - it's populated and just needs a small debug.

I'll still come back to the "well" here as I work on other ideas. I'd like to get about 15-20 OD projects done and call it a day (I'm already up to 10 layouts completed). Honestly, working on these feels like a cakewalk compared to some of the other stuff I've been trying to pull off the last year or two.

That all sounds pretty awesome.

Would you do sliders on the graphic fuzz or just pots? Either way itíll be cool. One possible thing that might make it interesting is if you could have the EQ work independent of have a switch for the fuzz. That way it could be a 5 band eq as well. But donít know if that would work with the circuit

If I may ask, why the sudden interest in dirt boxes? Is a lot of the VFE stuff going away making room for new inventory? Just curious.

It'd be cool to take a second swing at both the Grease Gun and Rump Roast.  For some reason I never warmed up to the originals (my problem, not the pedal design) and I never really understood why.  I miss my old Night Train, although I traded it for a 6505MH that has been my main amp for better than a year, so having a pedal version would be cool.

I'm very excited about the Systech coming up.

I've neglected doing any new overdrives for the last couple of years while I was putting out the VFE stuff. None of the VFE will be going away for a long time, rest assured.

Here's the second volley which completes everything I'll try to stock/prototype for 2019.

Crackshot - GreaseGun2
Arsonist - TC Electronic Spark Boost
Boneyard - Plexitone
Krusty Drive - Ibanez Crunchy Rythym (after I saw the schematic I couldn't resist)
SandStorm - Maxon SD-9
Dragonbeard - a super tricked out Expandora

Title: Re: Your suggestions on overdrives for mbp
Post by: madbean on November 08, 2019, 09:41:41 AM
Will the Boneyard be dual or single channel?

I had planned on it being 1.5 channels with switching between two gain pots but actually I think I could just do two channels, each having a separate volume output but share the tone control. I think I'll do that instead.

-------------------

I couldn't let go of the Graphic Fuzz suggestion. After listening to some clips I decided it's something I want to build so I took a pass at it. The layout actually was easier than I though with maybe the last 5% of routing getting a bit hairy. Two areas I'm not yet sure about are the power and switching.

The power is a 12v dual rail so I actually put on two options: one using a charge pump and 12v PSU to get the -12v rail and the other using one of the Murata DC blocks and uses a 9v PSU. I think probably either will work fine since the only question is how much juice the negative rail needs. I don't think it's going to be more than 100mA!

The other was whether or not to use the original FET based switching. I decided to stick with that for now. I'm pretty sure I know what to do to convert it to true bypass but I think I want to at least try the FET switching out first.

Anyway, here's the first pass at a layout. The eq bands are 9mm plastic shaft pots at the top. I like this arrangement since sliders are pretty much out of the question.
