This is a top 5 overdrive IMO and that is why I have built different versions of this pedal - but this is my favorite. I wanted to use my favorite Davies 1510 knobs so I moved the pots closer together and used a 3mm LED. I exposed the symmetry switch and used a female pin header to get a sub-mini toggle to reach the outside. The enclosure is a 1590b and the decal is film-free with a 2k clear coat. For jacks I have begun to use enclosed mono jacks. I socketed the IN4148s and used a soft-click footswitch - the toggles are both short-bat Tawaiy. I am always happy when my decals line up the way I need them to.

Notes

1. Wide board - at 2.2" × 2.25" × 0.5" the board is too wide for a 1590b. Fiberglass needs to be sanded off of each side of the PCB!
2. Enclosed jacks are larger than Lumberg 1/4" TS Open Jack - KLBM 3 so I had to sand off a bit of the outer jack plastic so they could sit under the board -
3. Shorter electrolytic capacitors are needed - PPCB has them - two short 47u ECs
4. 820N film capacitors - not a common value - these are very tall film caps and you probably need to lay them down as I did here - from Stompbox
5. 39n film capacitors - not a common value - from Stompbox
6. Symmetry switch - if you want to expose this on the outside, you need a sub-mini on/on toggle with PCB pins (pins need to be filed a bit in order to fit in the pin header- For hole drilling (3/16") it goes 1.5cm below the "Range" switch and you will need a female pin header or off board wiring to get it to reach the top of the case

Nice and neat despite the cramped enclosure! Great job!

Thanks Matt! These are my favorite enclosures. The PPCB board is more than a little too wide. If PPCB decides to revise the PCB I would appreciate at least a 1/8" shave.

You and me both... and that's a nice-looking pedal!

Nice to see that the sub-mini toggle/pin header method has found some traction!

PS - Holy 5lbs of crap in a 1lb bag, Batman!

Thanks much one of my favorite circuits and I’m waiting to make one so perfect that I have to keep it. Lol you got me turning my footswitch around now. Lol.

Thanks much! The method works great! I did have to file the PCB pins on the sub mini but it works!

I smashed mine with some long-nose vise grips

Ahem... check out the first Tommy I built. I used a full sized toggle and manipulated the legs.
