A couple questions for the PedalPCB Man or anyone who has built one of these...
That STRUCTURE switch, all it does is cut the gain? Seems semi-useless since the GAIN pot does that already. I'm building the Thermionic Deluxe, and rather than build channel B as a Brown Betty (which I already have), I'm going to build it as a Complex OD. Looks like I can leave that switch out and maybe use an A500K in place of the A1M for GAIN. Should work because channel B is intended for lower gain operation.
C14-R20 on the Complex OD adds a 6dB boost that starts at 7KHz and tops out at 14KHz. Who the Hell is gonna hear that? Not me, that's for sure. I might try increasing C14 to move the treble bump down 2 or 3 octaves. The TREBLE and PRESENCE controls are cut only, so I think a 6dB boost starting at 3.5KHz or so will work.
I might mess with D1-D4 on Channel B also.
Your thoughts?
