MINI OVERDRIVE PREAMP/666 (GREY VERSION)

Based on my original transition DOD 250 this is my version of the early "grey version" overdrive preamp from the late seventies into the early eighties. This uses original value components and the original "legendary" LM741 IC. My version has true bypass switching, an LED and a Boss style 9V input adaptor, none of which the original (or re-issue) DOD 250s had. Hand built in my new smaller stainless steel enclosures on custom designed Tym PCB's.
