One of my older vero layouts for the Benson Preamp that I posted on Guitar FX layouts forum a while back – updated due to the bass and treble outer lugs being the wrong way around…
I have previously posted the point-to-point version, but I forgot to post the vero layout at the time. I never actually boxed this one up, as I prefer the Fairfield Barbershop as far as JFET overdrives go.
It’s a JFET adaptation of a Benson amplifier pre-amp. Treble is a basic cap to ground situation – like a guitar tone control, and bass is cut, with the pot bypassing a small capacitor that limits how much bass can pass.
