So I built a second, smaller Madbean Rump Roast in a 125B, this one lightly modded via breadboarding and added an extra row to [lvlark's layout] for that large orange cap. Q2 is here a J113 (Q1 still J201, both Siliconix), 150k resistors were upped to 330k, gain 1 r up to 91k, output r down to 97k. Also some small cap value changes, bottom right down to 8.2nf, 1nf to 2.2nf, 680pf to 1nf, for those interested. Oh and a 33k or above is the only thing that makes white LEDs bearable to look at.
I just played it by ear as usual but sounds like the bright/high gain mode is more saturated/compressed, and the cut at minimum doesn't get as thin. I plan to record a side by side comparison but overall they're very similar, I mean it's a solid Madbean design at its core, and based on the Dr. Z Carmen Ghia preamp section. Of course I've never tried one of those, but for me this cops a wide range of very present, tube-like boost/overdrive, with an unusual tone control. Goes from thin and jangly to beefy with an interesting high cut/mid scoop happening in the last quarter of the rotation. I tried to widen or move this sweet spot further towards the middle but failed, still that zone does cool tone-shaping things with like fuzzes flyin' thru. I think I'm good with two of these, but definitely a great circuit.
The paintjob is white on white basecoat with black splatter, then a thin rectangle of white again, fluorescent pink and blue enamel letters, pink jellybean, some blue wash, some coats of gloss clearcoat.
