ARO70W GRANDTONE OVERDRIVE

RHODIUM ELECTRONICS  - ONE TRANSISTOR

One transistor fuzz-overdrive circuit, a transistor preamp circuit based on silicon BC108B transistor (Gold pin military grade) following a vintage true-bypass specification. An early overdrive diagram which it delivers transistor fuzz dynamic responses, offering a mid range boost at low settings, adding dialling features from cutting zone to overdrive to fuzz saturation territories. 

Please, note this is a vintage circuit that require isolated 9 Volt negative tip PSU. As a vintage circuit, this circuit behaves differently in front of different amplifiers or playing with different guitar pickups. Battery free pedal.
