  1. Built this one and it doesn't seem to work. Triple checked everything. I'll go through the schematic to see what I missed.

    1. it looks like the drive pot connections on this drawing need to go like this (at least according to the schematic on pedalpcb):
      Drive 2+3 should go to the row where Drive 1 is now, so that they connect to the 22k resistor coming off pin 2 of the IC. Drive 1 actually needs to go to pin 1 of the IC, where drive 2 is currently located. Not sure if this is the only problem that needs solved but the drive pot will definitely square up with the schematic this way.

    2. Thanks Chris. I also noticed that "Tea" 1+2 & 3 are reversed. "Tone" 1+2 & 3 are reversed.

  4. aaaaand built! everything seems to be working as expected. i built the current layout and added a cut at B4 as i mentioned before. i think it's safe to tag it. thanks, anders!
