Here's my latest build. A variation of the 1978 IC Big Muff.



Perhaps not the best wiring in the world, but it sounds good. The ciruitboard is just for having some place to mount the IC sockets. It's a 4558 & an uA741. There's an extra switch to toggle between two different diode-bypass caps (as well as not having any in the circuit at all). The fourth pot is a "body" control, basically just an extra tone control. And the DC jack is actually a 3.5 mm mono tele jack.

It made it a bit easier to get the "correct" polarity on the jack (tip +, ring - ) as opposed to the silly

center negative option.
I did notice that I too have some four digit 4558s lying around along with a bunch of film caps from the '80s & '90s so TS808, here I come!
