An old super rare DBA pedal which was a two channel fuzz. Here is the transistor channel which resmebles most older DBA designs; cascaded reverse beta transistor gain stages. Socketing your transistors is a must since you need to find ones that doesn’t gate too much. Also, there is a Filter control which is a variation of twin notch filter. Shape control is a simple ground lift for the filter circuit.
A big thank you to Nils at Moonn Electronics for the trace!
Schematic is avaiable HERE.
