Hello Everyone,
I am having issues troubleshooting this Stutr Build. When the effect is off I have sound from the guitar. Once I push the switch, silence. I took some photos and Have some voltage readings:
IC1:
1: 4.46 2: 4.42 3: 4.24 4: 0.01
5: 4.24 6: 4.19 7: 4.45 8: 8.85
IC2:
1: varies 2: varies 3: varies 4: 0.00
5: varies 6: varies 7: varies 8: varies
I re-flowed any questionable joints, no luck. I appreciate any help I could get.

Is R18 & 19 meant to be empty
according to the build doc, if you do not wish to have the speed indicator (d2) than there is no need to populate R18 and R19.
I don't think pin8 of IC2 should be varying. What voltage variance are you getting?
Upon testing again. There is no voltage to pin 8
you should have your supply voltage on pin 8. As your LFO is working apparently (varying volages on the other pins) you must have voltage there. So please check again; it should be a steady 8.something V.
Do you have an audioprobe? there's a new tutorial how to make one and you could trace the signal to where it stops.
