wow OG style board! looks good! 220k sustain pot? can't make it out.

200k. Among the many surprises we found in the original one we desoldered and measured was that they had reversed the pots at the factory from the published circuit. So the sustain was where the attack should be and vice versa. Probably a simple mistake, but it really adds a small amount more low-end. So we kept that aspect. Measuring all the components was a real eye opener as to 40 plus years of drift. Even the potentiometers had drifted. We tried things many ways, published schematics, some of the other builds values and our original's measurements. Our final values were decided by what sounded the most like the original. Interesting phenomenon-- when ABing fuzzes, you have about 1/2 an hour of objectivity. So that went on for a good month because we would just have to come back to it over and over.

ok so you kept the one off factory mistake? attack/timbre = 200k and sustain = 100k? Have I got that right?

Yes. We checked it both ways many times and even ran it past guru Tim Mead at Q2 Audio. The difference is very slight but a bit more focus in the low-end.

Looks great! Legit work.

Both pots higher value would be interesting!

Hey Uncle Bob. Good to see you on ILF

Damnnnnnn the guts are just as tasty as the enclosure!

A shot from powder coating

Amazing!

Wow, these look incredible.
I love when one specific individual pedal is faithfully recreated.
Gotta respect the amount of work that goes into getting everything just right.
Great job, dude.

v. interesting.

Totally love the enclosure! Sheetmetal, welded edges? So great with the knobs all on the huge top end panel...
