  1. Verified, I think? Not sure how the bass and treble controls are supposed to interact with each other. As it's laid out here, which looks accurate to the schematic to me, the treble pot is a high-pass filter that opens when the knob is turned clockwise - in other words, it's trebly when you turn it all the way to the left, counterintuitively. With the gain all the way up, this thing rips. It's got more gain than the OVD-1!

  2. Yep - the Bass pot connections should be reversed. Treble 1 goes to Bass 1, Bass 2 and 3 connected to row I. This circuit is really rad!
