Hey Bugg, may I ask what difference is between the 2 pcb versions? I just purchaced v1 with 1/8W resistors.

The new version uses 1/4W resistors because a few people had trouble sourcing 1/8W resistors (I get mine from Tayda), also the component placement was made a bit more symmetrical to satisfy my obsessive tendencies.

Aside from that, there is no difference... The tone, circuit, wiring, and control layout is exactly the same.

I used the first bugg board and it was tight with 1/4 resistors but worked fine. Which cap is causing the oscilation? I may switch in the new cap because there is a killer George Lynch tone to be dialed in with the oscilation but I don't want it all the time. I love this circuit.

I used 470pF instead of 120pF, no oscillation whatsoever.
If you scoop, it sounds like poop!

I would socket that space and try different cap values
