Electro Harmonix Bass Big Muff

 Per request. Was a bit hesistant to upload this since there are three missing cap values. But socketing some values should get you close enough.  Note that I omitted the ferrite beads since they are overkill and I also omitted the direct output jack.

Schematic is avaiable HERE.

    2. The TL074 and LM324 have the same pinout, so you can use those to check your build while waiting for the TLC2264. Good luck!

  3. ok! i build this using bc550c and tl074. there's 17 links instead of 16 and 40cuts. sw5 on n1 i connect to sw1. when i test it there's a sound audible somewhere in the distance ( even less output then the pedalpcb decadence ) but when i remove the ic, i get output, not mega loud but theres much more output. pots seem to work. c31 i put 10uF, c31 68 nF and c38 470Nf but i have to test further and offcourse no output with ic ! now its time to rest lol but wanted to make sure that i tried this layout / request

    1. have been tinkering with this (with the correct ic) but when i remove the ic i get somekind of usable output but it is not loud enough , controls all work , almost no output with ic in socket, more output without ic but still not loud enough.
