Thanks for the info.
I'd like to do something to alter what I'm getting, as I find the non-cut setting almost unusable on most of my guitars... It sounds pretty good with the tone cranked into my tele, but mostly I run the bass cut setting and the tone around 9-10... The gain is also pretty lacking, imo... but I just attributed it to replicating a legit Plexi, which isn't a really gainy amp... and most old Marshall's are bass heavy amps (they are based on a bassman circuit after all)...
I've not really explored much on if B Wampler was trying to make a legit "amp in a box" with this pedal or if it was supposed to be a distortion circuit that emulated the character of a cranked plexi... kinda like the "Bluesbreaker" pedal.
If I could add a bit more treble/less bass and bump up the distortion a touch, that'd be killer. I'll recheck my bias again but I biased it once, let it "cook" for a bit by leaving it on, then checked bias again, running it 4.5v at each drain.
When I built it, I used thru-hole J-201's I had bought from Mouser, and they were FRIGGIN EXPENSIVE... Probably should have bought smds on the adapters to be sure, but I had them already and decided to roll with them. Mouser is reputable, and had they been fleabay J201's I probably wouldn't have used them... but I digress...
