Hey just built up the Stockade and having trouble getting it working. Thought I'd see anyone could help. I'm getting guitar signal while bypassed but no sound when engaged. LEDs work. Switches work. So I used an audio probe to see where it drops. I'm getting signal up to the buffer toggle but no further. I suspected the IC so I swapped it with a spare and then again with different one that should work and neither changed anything. Tried to flow solder on a few joints, didn't change anything. SO I'm pretty stumped at this point. Any ideas? THANK YOU
