I was messing around with this on paper and wanted some more experienced eyes to look it over. The only real changes are adding an extra eyelet on the board for the extra V2 grid stopper, and I moved & changed the NFB. My idea is doing it like a Princeton Reverb and making the bypass cap switchable, the ground side being on the switch. The plan would be regular Harvard clean, then the gain boost on a switch or single button footswitch & RCA jack, like a lead boost. But, keeping NFB in the circuit - I've tried it with no NFB and it's just painfully bright and too rowdy. Thoughts?
