Prescription Electronics Dual-Tone

Vintage Prescription Electronics Dual-Tone in excellent condition! Handmade right here in Portland, OR. There is no date or markings inside, although looking internally it is clear this is probably an early version. Hardwired, some goop to conceal values/components. This is basically a two-stage overdrive in the light/medium gain category, and it has a “Fat” switch to change the EQ. Everything works- it will run on a 9-volt or wall wart PS.
