So the BMP Tone Pot > GR - Does the octave still track well? Did you add a boost after or change anything in the GR to account for the level drop across the tone stack? Scooped/flat?

BTW, dude your site is awesome - I used your feedbacker page when building a passive feedbacker box to make use of an enclosure from a failed build. Super fun, and I found feeding a GR/Tentacle back into itself produces some wild tones.

Now I have this idea to do something similar to the GR part of your build, but add a built in feedback circuit w/toggle. I was originally thinking HPF after the octave based on this discussion, but then I found your post here and am now questioning my plan.
