ADHD

Building an ADHD without optional Buffer board.

There is no build doc so I don’t know if there’s something in there that I’m missing but when I engage the pedal, even with all the knobs maxed I only get an undistorted signal slightly lower volume than bypass.

Tried several OP Amps.

C2 and C5 should be 220pF, not 220nF.

Reminds me of a post I made about a week ago about not buttoning up a build before I tested it…
