So I am new to pedal building and as my second project I decided to build a DOD FX25 from http://topopiccione.atspace.com/PJ11DODfx25.html
I got everything together and no sound. I ran an audio probe along it following the input and lose signal on the far side of R23. It sounds like the circuit is complete (ie no noise) but no guitar sound either. I swapped out the resistor and still no sound. Is it possible it is not the resistor but something else on that side of the circuit? IC2 maybe?
