Based on the old Dallas Rangemaster and the Catalinbread Naga Viper, this Treble Boost is the perfect add-on to give some punch to a clean or distorted tone. Very simple circuit with original 2N2222 can transistor.
Boost control the volume output, Heat is the Bias drive of the transistor and Range is a low frequency cut knob. The Moth is good for single coil pickups tone, humbuckers, to tighten high gain stuff, to boost a low signal, anything really.
Power Consumption : 1mA
Voltage : 9Vdc center negative
