Before you swallow them? :) Sorry, I couldn't resist. Maybe you have a pedal where the opamp can be swapped? Single opamp.

If it works, why change? :) I've tried switching to Kicad several times and keep coming back to Eagle. Switching is difficult once...

I've seen at least one build report for this already so I know I'm not the first. This was in a dump of Gerber's from @szukalski, he...

I've build several Tone Bender Mk. III x Big Muff circuits, and this one might be my favorite. You should build one if you haven't...

Once you have the transistors matched, the fun begins with turning the bias trimmer, like a ham tuning a radio to a weak SSB station...

Testing the circuit on a breadboard now. three sets of matched JFETs. Same settings for the first three samples: speed, depth (max)...

This yellow sulfur is quite good. Unfortunately, local suppliers only offer a powder with a smooth finish :(

OMG. YELLOW SAND IS FINALLY HERE...

Yes, my switch footprint is technically on the wrong side of the board.

@Robert - it's me again... I just wanted to make sure these are the correct connections for the dpdt. The connections in the schematic...

C3 from 100n to 100u C5 from 2.2n to 22n

Thanks for the tip, I'll have to check them out. I only have versions R and Y.

The MMBF5458 is generally unavailable, but the Mouser website offers suggestions for similar transistors. For example, the 2SK932...

I highly recommend two detailed tutorials from Phil's Lab on PCB design in Kicad9. They're quite long, but the amount of practical...

Almost there... 59 board is ready.
