Title: VFE Mega Pedal
Post by: fair.child on March 12, 2018, 11:55:01 PM
TLDR; You can read the whole story here (https://medium.com/@swirl.fx.pedals)

Here's the final result of my VFE Mega Pedal

I can't help you with any of your questions. But I salute you in your effort. That is quite the ambitious build. I wonder how much it will weigh?
Title: Re: VFE Mega Pedal
Post by: fair.child on March 14, 2018, 10:23:29 AM
No worries, I am guessing the weight will be around 10-15 pounds (just a blind guess).
Title: Re: VFE Mega Pedal
Post by: bsoncini on March 14, 2018, 11:54:02 AM
Weight and size is always the first thing I think of.  Driving in paris sucks so I have to put all my pedals in a bookbag and take the subway. Anyway good luck.  You planning to wait for all of these vfe pedals to be released to start?
Title: Re: VFE Mega Pedal
Post by: fair.child on March 14, 2018, 12:32:49 PM
Well, I will combine some of parts from Brian. Plus, there are some fuzz pedals on the board which Brian is not going to release (or at least I'll say unplanned for him). I'll do a head start. As always, right now I am trying to find where I can get the PCB fabricated nicely. I've seen elecrow and advanced circuits. I'll try to contact elecrow first, rather than go with OSHPark. The reason is I don't want to have three same PCB's at one order. Plus, comparing the cost I am betting the most expensive build I've ever made. I don't mind for how heavy it's going to be. It's the matter of the fun building it.
Title: Re: VFE Mega Pedal
Post by: Aentons on March 14, 2018, 02:38:18 PM
I had entertained the idea of making a mini mega pedal (single row) by using individual 1590b cases and leaving off the input/output jacks and routing a hardwired disconnect through a hollow bolt across the input to output holes, and using a spacer of some sort to compensate for the cases side slope.

I have 4 vfe pedals on my board right now and if I turn on 2 or more and one has a charge pump, I get ungodly amounts of noise so that has deterred me somewhat, so watch out for that. (Merman>Enterprise>AlphaDog>Triplet)
Title: Re: VFE Mega Pedal
Post by: fair.child on March 14, 2018, 03:15:49 PM
That is the reason he has an extra EQ on the switching board. Basically, the Mega pedal will utilize the Mega Board EAGLE file. The schematic doesn't give much info but the Layout has a buffer and one huge PIC switching which I am still tracing out. I am working on populating the GPIO pinouts from the PIC to I/O of the board. Once that task is completed then I can start ordering and planning the PCB.
Title: Re: VFE Mega Pedal
Post by: fair.child on April 05, 2018, 12:37:48 PM
After careful planning and continuing the story plus VFE fever, I decided to go with this Mega pedal chain:


1. Merman - OSHPark
2. Alpha Dog - MBP
3. Pale Horse -MBP
4. Triplet - MBP
5. Blues King - MBP
6. Bumble Bee - OSHPark
7. Rocket EQ - OSHPark
8. The Scream - MBP
9. Mini Mu - OSHPark
10. Tractor Beam - MBP
11.  Choral Reef - MBP
12. Old - School - MBP
13. Mobius Strip - MBP
14. White Horse - MBP
15. Focus - OSHPark
16. Blueprint - MBP
17. Yodeler - OSHPark
18. Fiery Red Horse - Ralfg

Quite different than the real Mega Pedal but I challenged myself to build something different. Also, I plan to put all the modulation on the fx loop, not just daisy chained it. I figured that I might print 9x2 board switchers instead just run 18 mega board.
Title: Re: VFE Mega Pedal
Post by: fair.child on April 09, 2018, 06:18:43 PM
Update:

11 boards acquired, 3 boards in the fab and 4 more boards to go. Getting close!

Just got the latest board from MBP and started to build up Alpha Dog, White Horse, Pale Horse, and Merman

I tend to take the build steps slower and take a more careful read. Still waiting for the Blueprint-MBP to released, Bumblebee, Mini Mu and Rocket EQ.

Okay, folks, Nigel at Honey Bayes did a huge favor for me in terms recreating this $4k pedal (I didn't know it costs much).

He took one picture and bravely opened his VFE Mega Pedal.

Attached is the snippet of his VFE Mega Pedal. Now, what do you guys think? Plus, there is a TAP tempo.

Um, that big DSP processor board has an electro harmonix logo on it. Is this perhaps a different multi pedal?

I am highly doubt it. However, thank you for catching that. I even didn't see that EHX logo. The picture is not in high res from Nigel. He said that "the switching system was not implemented as it does render the unit somewhat difficult to navigate, particularly when using it as a performance tool. In the studio it's great, particularly the inclusion of the patchbay on the back, and visually, it's just looks amazing."

That quote implies that Peter didn't finish up the PIC switching system instead using 12F509 for controlling each of the effect. I am exploring now and thinking an Arduino could be potential solution for this switching. Otherwise, I will try to utilize the 12F509 from Brian and add a toggle switch controlling the signal line. I don't know yet and I am figuring it out as I keep build them.

Update Today:

Most of the parts are populated and ordered extra resistors from Mouser. That 14.3k and 1.43k are the real pain, though it says I can use 1.5k or 15k. I will stick with the real values. I am also waiting for my Blueprint to come. Haven't heard anything back from OSHPark, hopefully in next day or two, I'll hear about Bumblebee, Mini Mu, and Rocket EQ.

Buy a bag or two of carbon film resistors, and meter them, then pick the closest to the value you want :) (CF have a bigger range than MF.)
Title: Re: VFE Mega Pedal
Post by: fair.child on April 11, 2018, 11:08:09 PM
Thanks, alanp. However, I just did order through Mouser. My intention was trying to use all my leftover parts. It seems it's going that direction. I ran out of 100nF, 10nF, 22nF, 4n7, and others. Finally, the build that costs me running out of caps, resistors, and diodes. My 1N5817 is going to be out soon and 1N4148 is already out. I am quite happy with the process.

Hmm.. To me it looks very different from the usual VFE boards and it seems unlikely to me that Peter would redesign all the pcbs. Plus, he always used the hatched GND planed, which I can't spot here. What bugs me most is the dual pot and the small pcb in the front that seems to just dangle around. I wonder where those are intended to go. Just my two cents. Good luck with your build!

Post by: fair.child on April 12, 2018, 01:15:51 PM
Well, either it's true or not, at least Nigel tried to give an useful pointer about the switching. I think the most challenging part is the switching. I am still working on the latch system using the PIC and swapping around with Arduino as well. I can envision this is going to be an amazing build.

Bumblebee, Rocket EQ, and Mini Mu have just done from the fab. Going to plan for the next step for the rest of the pedals. Focus and Yodeler might be the great candidates.
Title: Re: VFE Mega Pedal
Post by: fair.child on April 12, 2018, 04:39:24 PM
Update. I got the Yodeler sent to the fab OSHPark. As usual, set of 3 and I got one extra, so let me know if anyone is interested.

ONLY One Left...... which it's a Focus board. Please MBP, next development be the Focus. Please, Brian if you happen to read this.

No prob... I might be interested in that extra Yodeler. I'll send you a PM.

I thought I remembered seeing a picture or video of the inside of a VFE mega pedal somewhere in the vast expanse of the internet. I could be wrong but I think I recall the bottom foot switch section being basically empty except for the switch and wires coming down from the top part. I'll try to recall where it was.

I also just realized the Megaboard's Switching set up is a board in the Patreon pile.

Good lord its terrifying

(how on earth did I miss this thing)

Oh and apparently it didn't actually work: "This is the switching board used for the massive, 18-effect MEGAPEDAL giveaway. We were never able to get the master switching controller working, and it is no longer compatible with the current program in the 12F509 MCU."  ...now I want to know what madness they DID end up going with.

That board costs around $144 on OSHPark. Freaking expensive and it's a gamble to make it work. I just followed the design pattern of the switch. Start it over is way much easier than print this board. However, I learned one thing from this Mega Pedal. Apparently, the TSB switch can be reusable. The idea is to divide the 18 boards by two. So, technically it's 9x2.

I really want to do YouTube video and document my progress/process of thought. It might be beneficial in the long run if anyone wants to recreate this gigantic pedal.

Mega Pedal that I found just only two. One is the demo (cars decal/printed) and another one is the Kroak. If anyone can find the others, that would make this journey become interesting.

To be honest, I really like Yodeler more than Springboard. I know this build will contain Blueprint and Mobius Strip which they are cool. However, I just don't feel that Springboard will be a good fit for my needs. I want something that can run delay+verb at the same time. Thanks to Peter, VFE does have Yodeler.

So far Somnif and you are in the pool for Yodeler. I also got a recommendation from somnif to remove layer 2 and layer 15 from the EAGLE board.

For those wondering why: Some VFE .brd files process as 4-layer on OSHPark. Layers 2 and 15 are blank, empty data, but OSHPark considers them as valid layers for some incomprehensible reason and doubles the price of the fab. Removing those two layers changes nothing (as far as I could tell, and I dug deep) and fixes OSHParks automated brain process.

I tried to find more information about Mega Pedal. Based on the webarchive of vfepedals.com, here is what I can find.

The MEGAPEDAL was first conceived as a promotional giveaway, which we gave away to one lucky customer in July 2012. It contains 18 VFE effects, input/output buffers, tap tempo delay, a full patchbay on the back, and one seriously sweet graphic. We plan to upgrade it with programmable switching very soon (this is included with any future orders). After several requests, we decided to make the MEGAPEDAL available for purchase. We have the parts to only build a few of these. You can choose to have the stock version (see features tab for detailed info), or customize the color/knobs/graphic/effects to your specifications.

The MEGAPEDAL takes a very, very long time to build. It involves many steps, some of which must be custom done by our enclosure supplier. Because of this, it will likely take 3-5 months to build. We will keep you updated with every step of the process. Pricing ranges from $3500-$5000, depending on the options chosen. Please E-mail us at sales@vfepedals.com to get more information or an exact quote.

MegaPEDAL takes a very, very long time to build which it is a true statement. Careful planning, scratching head, and try to make everything work. Though it takes a long time to build, I do really enjoy the build. Just don't know why it keeps making me excited.

The only problem is....wife is not happy I am spending too much time on soldering... she has been asking me to sleep early, not late.  8)  8)  8)

The journey continues  ;D  ;D  ;D. I have calculated my cost. So far, I have spent $982.54 for the build. Enclosures are coming and extra parts (Mouser, Smallbear, BLMS, and Tayda). Just got Mini Mu, Rocket EQ, and Bumblebee boards from OSHPark today.

(http://preview.ibb.co/npDTMn/IMG_4685.jpg) (http://ibb.co/k9vxE7)

Place them in the plastic bags so I can easily manage the builds.

The question I do have. There is a buffer coming into the pedal and as well KNOWN issue with the PIC/switching programming. What are those known issues with the switching? I am guessing the programming should be similar to the Clickless True Bypass Relay by Coda on the PIC18F44K20. Also, my thought, the programming would be dedicated to controlling the patch bay.

The enclosure could be 1456WL3WHBU (15 deg slope) OR 1456WK4WHBU (30 deg slope)

The switching MCU used on the Megapedal builds (yes, there were two of them) used a slightly different pinout & program than what I've been using the past few years. The schematic/board file would need some updating to work with any MCUs sold on madbeanpedals. Here's a link to the current pinout:

https://www.dropbox.com/s/rpd8u9bbyt7f4xy/MCUpinout.png (https://www.dropbox.com/s/rpd8u9bbyt7f4xy/MCUpinout.png)

The original plan on the Megapedal was to create a programmable switching system, but we weren't able to get that part fully working. On the two builds I did, I simply omitted the massive PIC controller and wired the switches directly to the controllers.

I assume you have the Eagle schematic & board files for this build. You can always go in and modify the switching section to match the existing pinout. With the way the circuit is setup, you would want to connect the J175 (soft switching) and BS170 (LED switching) to LO. It's counterintuitive, but both are setup to turn "on" when that pin is at 0V.

As for the enclosure, you definitely want the 15-degree slope. That's what I used.

This picture is definitely not the Megapedal I built for Nigel Honney-Bayes. That's my original Megapedal, which I started before VFE Pedals existed. I re-housed and modded several digital effects into one box, including a Roland MIDI foot controller.

The journey continues...

Today, I got a chance to complete the drilling jig and drilled the enclosure.

The result..... the enclosure is a tight fight for 18 pedals
(https://preview.ibb.co/ecMt9H/1.jpg) (https://ibb.co/hap23c)

I am still waiting for my Focus board and parts from Smallbear before I can finalize the main board leftovers. The switching board is done and going to be installed soon.

(https://preview.ibb.co/dj6RUH/2.jpg) (https://ibb.co/je3jGx)

I was so happy when the drilling finally finished. It was tedious.. very....
(https://preview.ibb.co/hORh3c/4.jpg) (https://ibb.co/czMFOc)

I had an idea to put together a jig. I use Poplar board from Home Depot and drilled it
(https://preview.ibb.co/jTRh3c/5.jpg) (https://ibb.co/kFiUic)

Everything is a tight fight and there is only a small room for error.
(https://preview.ibb.co/kkhY9H/6.jpg) (https://ibb.co/mHJ6UH)

I created the drawing template from Hammond STP file and used the MBP VFE template to figure out for 18 pedals
(https://preview.ibb.co/jWpD9H/7.jpg) (https://ibb.co/cvZPGx)

Also, I did a pre-layout the Hammond case first before I go and drill the enclosure.
(https://preview.ibb.co/hDhBwx/8.jpg) (https://ibb.co/goqaOc)

I can't screw the pots using the Poplar board but I got a pretty decent measurement.
(https://preview.ibb.co/chg4Gx/9.jpg) (https://ibb.co/mpWRUH)

Like I said, it's a tight fit and some 9mm pots aren't lined up properly. I might wiggle the space a bit.

I have jumpered them. Alpha Dog, Merman, Pale Horse, Choral Reef are verified working. I am too tired to test the rest, so I assume they work if one of them needs debug then I'll isolate the problem.

Trust me, you won't believe what you'll see next for the switching. It's going to be exciting and I tend to slow down a bit to enjoy the build process.

That is WAY too much work.  Nicely done though, it looks like it's coming together very nicely.

If you use a tapered reamer you can open up the holes just enough to give you a bit more room to play with without screwing up either the finish or the hole size.  Use a handheld one and use light pressure and check as you go.  It's saved my butt more times than I can count.

I used the tapered reamer to clean up the holes. I still need to give a little room for 9mm pots. I am a true sucker at drilling 9mm. Fortunately, it come so together with my drill template/jig I created.

The only problem now is the artwork.

That is very excellent question. I'll add 5 separate D.C. Outputs for fx clusters. I know it's not the prettiest way to do it. Peter Mega Pedal only had one D.C. Out for all the chains. My approach is different. Each of the D.C. Output will have one regulated input.

No, I don't have a name for it. However, I ordered the tap tempo form UK Electronics and going to incorporate that for this board.

Which Tap Tempo is it? If it's for the 2399s then you should use a Taprecise.  You could get a couple of those 9v multi tap transformers. AND aren't there different requirements like split rail and 18 volts on some of the VFE pedals?

That is correct. I will still use the Original Switching Boards. The enclosure is big enough to fit all of them. I will have the Taprecise. However I am betting since I have created a separate Loop/ cluster system (Updated on Page 1), it will be hard enough to fit the pots.

The Tap Tempo is from uk-electronics.

Here's the way to hook up the tap tempo. Hasn't proven yet but I got the logic behind it.

There is a lot of explanation about how to wire up the board. I believe the marked TAP on the board to be jumpered. This is the pin out of the 10k rails. It turns out it works as lead points, just like connecting between the main and switching board. There is a label A on the main board which I have no idea of what it is.

Finally, after long hours of planning and errors have been made, I finally came this far.

The graphic arts made by Photoshop and printed using LaserJet printer @Office depot using Waterslide decal.

(https://preview.ibb.co/f11Gy8/IMG_4769.jpg) (https://ibb.co/dMikrT)

I did the labeling with the waterslide as well. The base color paint for the pedals are Krylon/Rustoleum/ACE Enamel

(https://preview.ibb.co/miqWWT/IMG_4771.jpg) (https://ibb.co/nFR5rT)

(https://preview.ibb.co/hkBGy8/IMG_4772.jpg) (https://ibb.co/iJnpJ8)

I cropped the 20"x6.5" long. It ended up using 3 sets of the waterslide paper.

(https://preview.ibb.co/h5Lby8/IMG_4775.jpg) (https://ibb.co/fQ15rT)

I am going to spray it again with the MinWax Polyurethane after the label dries. After that, I go with the wiring. I experienced "honeycomb" paint several times. This is the reason I suck at painting (to be honest) and I always keep redoing it (sanding/primer/etc) again and again.

I was so frustrated but at the end, I am happy where I am at now. Hopefully, it won't get me honeycomb issues after the Polyurethane.

Yes, I did. I use this product from Sunnyscopa.

https://www.amazon.com/Sunnyscopa-Laser-Decal-Standard-sheets/dp/B076VFHV1F/ref=pd_bxgy_229_img_3?_encoding=UTF8&pd_rd_i=B076VFHV1F&pd_rd_r=TBHCREBRZP7N13CCTXD6&pd_rd_w=bhMHM&pd_rd_wg=rxdwX&psc=1&refRID=TBHCREBRZP7N13CCTXD6

I cropped the image and trimmed the images precisely over three sheets of the decal. I tried this method three times. The reason I did three times because I was impatient to do waterslide without noticing the base paint was messed up by the painter's tape.

Redo it second times, didn't like the result and got the best result at the third. Wife was mad because I spent all night long just to paint, sand, etc.

While I am writing this, I am also in the process putting the main boards first then do the switching board. I'll post more pictures soon.

Major Updates:

1. I am close to complete the project!!

(http://preview.ibb.co/eTgOi8/IMG_4788.jpg) (http://ibb.co/gsZyGT)

2. Here's how it looks like for the wiring. I used blu-tac to stack the control boards. One thing I need to tell you, it was a tedious work. Not fun at all. The populating main board was fun.

(http://preview.ibb.co/d0jb38/IMG_4786.jpg) (http://ibb.co/bS83i8)

3. I added the TAP-TEMPO for Blueprint. Finally, I got everything hooked up for the tap tempo (Thanks to Aentons for the pictures).

Overall, I am extremely happy where I am at. Very close, folks, very close! The next step is wiring the Ground/VDD bus. After that, I'll move to the testing each of the board functionality which is finger-crossed.

Alright,

So it's up and I have been testing each of them through the looper.

(http://preview.ibb.co/fQ02Fo/IMG_4803.jpg) (http://ibb.co/mLwL1T)

Here's the gutshot on the inside

(http://preview.ibb.co/h4Tdo8/IMG_4800.jpg) (http://ibb.co/b9WL1T)

The wiring is complete spaghetti.

My thoughts came to sweet and sour fruition. Here's the report.

1. I gotta debug White Horse, Bumblebee, Mini Mu, Rocket EQ, Triplet, and Blueprint.

If you guys have any idea in terms of debugging, please help me out.

White Horse: Whining and oscillating with the sustain knob turns up.
Bumblebee: Auto Swell doesn't work
Rocket EQ: The boost seems to be dead and no output when the boost is all the way up.
Mini Mu: No output and wah oscillating in the background.
Triplet: The Octave all the way causes whining and squealing noises like White Horse.
Blueprint: No delay, although the tap tempo works (verified switch tapping and LED blinking).

2. All the OD/Dist/Fuzz work (Pale Horse, Blues King, Merman, Scream, Alpha Dog, Focus, Fiery Red), Reverb/Delay work (Mobius Strip/Yodeler- nicely done), Modulation (Tractor Beam, Choral Reef, and Old School) work.

3. All the switching works nicely. I am thinking upgrading to 1776 Effects relay switch instead 3PDT.

Once I figured out the issues of those 6 pedals, then the VFE Mega Pedal is alive!

Post by: fair.child on May 24, 2018, 11:39:26 PM
Thanks all for you guys support. I've found the culprit for the White Horse. It was the BS170 on the clipping section. I pulled that off and changed to socket. Replaced them with 1N914 like Timmy. Voila! It works nicely.

Going move up to Bumblebee soon.
Title: Re: VFE Mega Pedal
Post by: fair.child on May 26, 2018, 12:15:04 AM
Okay folks, quick update!

Triplet works now. The culprit was the Ge Diodes I got from evilBay. I swapped with 1N270 and 1N34A and everything works nicely.

Rocket EQ works as well. It's a very nice Parametric EQ Pedal. I can get a wah-type of picking (think like chicken picking style/Richie Kotzen/Guthrie Govan) style with this pedal. The culprit was the dual-gang filter pot. The lugs need to be soldered properly both at the top and the bottom. Re-flowed the solder joints and voila! works nicely.

Still having the problem:

Bumblebee- I can't figure why the reason I never got the swell works. Also, I created another issue. The Volume doesn't work. I might need the closer look at the schematic level and try to debug it from there. What bothers me a lot the trigger for the swell doesn't work. This bothers me a lot. Reflowed, cleaned with alcohol, and Dexoit, it still doesn't work. I suspected I wired the Optocoupler wrong but it didn't. I will debug from the voltage reading and scope next. There are some transistors need to be voltage checked as well. I swapped the 2N5457 with the 2N5952 and flipped it. The Vgs for 2N5952 I am using is 1.47V which it's still within recommended ambitious range from Peter.

The mini-mu - a similar case with Bumblebee. I haven't spent much more time on this instead I really want to focus on Bumblebee. 

Worst case, I just created OSHPark batch for these two pedals. I planned to rebuild it again and do some tuning with the JFET.

I haven't touched the Blueprint yet but for what I am happy the Tap Tempo from UK Elec works controlling the Time Potentiometer of the Blueprint. The issue with the Blueprint is I got the signal but no delay. I had tried to swap the PT2399 and still no luck. My next guess probably is going to be go check the voltages.
Title: Re: VFE Mega Pedal
Post by: fair.child on May 26, 2018, 03:33:17 PM
Couple pictures of debugging! I finally got the Mini-Mu working. The problem was the chain after White Horse. The White horse itself has its own independent gain and when I turned everything up they become noisy and whining everywhere.

I decided to rewire the I/O for the Mini-Mu. I put it in Send/Return with Delay/Reverb. This solves the problem and helps to get better sounding.

The only things left are Bumblebee and Blueprint. Very close!

I had the same issue with the Blueprint and it ended up being the back of a pot touching a trace, given all the sockets (and long leads) underneath.  I generally don't use plastic caps on the back of my pots but it would have saved me here.

BP is nothing crazy special given all the choices we have around here but definitely a nice pedal.

I have no idea how you have the patience to put this beast together but again, very nicely done.

Okay, it is working now WITHOUT the tap tempo. I reverted back to the non-tap tempo version. I am debugging to board level now to verify the signal chain flows correctly. It seems the JUMP for connecting the TAP and 1K needs to be jumpered. I am verifying this now.
Title: Re: VFE Mega Pedal
Post by: fair.child on May 27, 2018, 06:57:03 PM
Alright, Tap Tempo works. However, it needs a real modification on the Time Pot. I can't use the JUMP and TAP silk-screen.

Here's what I've done for the tap tempo.

1) Build the Blueprint based on MBP direction (JUMP silk screen pads need to be jumpered). Leave the TAP tempo alone.

2) The tap tempo from UK Electronics works by manipulating the Pin 3 and Pin 2 of the Time pot. Also, the connection of Pin 6 of PT2399 can be jumpered from the JUMP pad near with the 0.1uF MLCC PWR cap

3) The 5V and GND can be connected on the 10K rails (on the top of the 22p). The second pin of the rails from the left is the GND and the third pin is the 5V. The tap tempo power goes here.

Beautiful, and my guess is priceless :)

It's not an injoke. Apparently, it was an issue with the imgbb. I just fixed it. All good now.

Alright, so quick recap!

1. I sorta fixed the Bumblebee issue. It was with the 2N5457 though I am still waiting for replacement boards from OSHPark and started all over again. I'd highly recommend use 2N5952 for Bumblebee with recommended Vgs from Peter (around 1.4-1.5V). It will produce the longest swell. Mine is 1.12V. I am ordering some 2N5952 for testing later on. Be in my mind that the 1uF doesn't need to be a tantalum, however, the .68uF needs to be a tantalum.

2. Since it's a massive pedal chain, I added Unicorn Buffer Breath for IN and OUT buffer. Adding Buffer for I/O is the best decision I've ever made for this pedal. No more squealing/ high oscillation/ whining from high-frequency attenuation and it does sound way much cleaner.

3. I've added relay bypass from 1776 and again, I am very satisfied with the result. It's way much cleaner and nicer build with it. I daisy chained the Relay bypass using the extra +/- pads. It's very useful.

4. It's a massive build. So far, I have spent more than 100 hours to build this including errors, drawing the artwork, schematic, planning, etc. It's a real pain, challenging, fun, a lot of sweat, tears, desperado, and finally, it's done. A lot of effort understanding the circuit and looking at the schematic. Right now, I am quite familiar with what Peter has done for the majority of VFE product lines. I sort of understand where the idea came from and the inspiration to build a better design. I think this is the most important thing overall.

5. If you're tempted or inspired to build your own, I'd recommend creating the new design of the switching. The switching is the most interesting thing. So far, I have been fun learning PIC/ATMEL stuff. As a reference, you should do 9x2 switching board if you want to daisy chain it. Otherwise, figure out the puzzle of Mega Pedal switching. I know I am little bit cheating by adding the 1776 relays and switch them together without adding the patch bay. But, hey, it's my build and I picked different variances of VFE pedals I might use as one giant pedal. So far, it works for me.

More than 100 hours. Out from what my wife has counted.

That is some fantastic work. Shoot, even I don't have the guts to attempt something so ambitious! You should be very proud of your work. And, keep those pics...I sense a good build of the year contender here :)

Congratulations on this massive undertaking.  In addition to the technical challenges, the painting on the board, decals, and knob choices look fantastic!

The only obstacle to winning will be creating a demo video of reasonable duration to fully show it off.   ;D

Does the pedal weigh more than your intern?

He is a big boy. Surprisingly, the pedal weight isn't as heavy as him.

Those colored nuts on your footswitches look great.   Where did they come from?

Found them on the internet at lovemyswitches.  I didn't even know those existed.   Nice touch for your mega pedal!

Didn't see your question, I apologize. Yes, it was from BLMS, anodized nuts. They are really nice and work as label for the LOOP/CLUSTER.
