Mach 1 Overdrive

Compared to the Greer Lightspeed, this overdrive targets one of the most acclaimed low-to-medium gain pedals of recent years — a circuit known for its transparency, lively pick response, and the way it seems to make an amp simply sound more like itself, only better. The Lightspeed earned a devoted following fast; building your own is a smart route to those clear, amp-in-the-room tones.
