Reeves Electro
Switchable Transistor Fuzz
The first release in the new PCB based Daughterboard series, built entirely by Izzy Reeves.
A single transistor fuzz, although the Darlington Flyer is switchable between two very different sounding transistors. One is a 1979 Motorola MPSA013 Darlington for smooth, compressed sustain and the other is a late 80s Philips Silverface BC546 for a much more open, gritty and slightly gated feel.
