 Schematic is avaiable HERE.

  1. I built this but unfortunately something is wrong. No output. I briefly got some gain sound when wiggling the op amp, but nothing now. I will troubleshoot in the morning. Also, you have two (2) 'Tone 2' markers. Looking at the schematic, it seems the top 'Tone 2' should be marked 'Tone 1'. Looking forward to fixing this one.

    1. Looks like there is a missing 1K resistor from pin 1 of the IC to the 15n capacitor (?)
