Tym Guitars Mini Overdrive Preamp/666 (Grey Version)


Tym Guitars

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.

My designs are inspired by the classic old units but with modern components and appointments and many options like true bypass or non-true-bypass switching, LED's, added "active" tone controls, boosts and "Boss" compatible 9-volt adapters. NONE of my pedals use batteries.
