Hello, I just finished building my lazy sprocket build, however I am having some difficulties. I own [for refrence], a function generator with square waveAM modulation that I can use to test the attack, an oscilloscope, a DMM, and a bench power supply.
The pedal works in bypass, but when I turn it on there is complete silence. Additionally, the voltage between the input and ground stays at 0 when on.
I have looked around on previous posts and have tested the OP amp pin 3 and do not see my signal there and I have tested op amp pin 6 and it stays at a constant 4.6V. This is independant of knob or trimpot position. But I think the big issue here is that my signal across the input jack dissapears when the pedal is on.
Shorting the tantalum cap gives me full signal in the output.
Do you have any recommendations for test points, either for DC voltages or for signal? Does anything pop out to you immediately? Thanks!
Here is my circuit board, a few notes
I was missing a 47nF cap so I soldered 2 22nF caps in parallel
I had a very hard time attaching the purple wire into S2, so I soldering the purple wire into a white, solid core one
