THE FORBIDDEN WEAPON
Powerful, transparent and noiseless class A Mosfet booster, useful to enhance low output pickups, push an overdrive or increase amp distortion, keeping the tone.
High impedance input and low impedance output makes it an excellent preamplifier for any electric instrument. It can be used as a buffer: keeping the knob within half range the input signal is just slightly amplified.
Works great also at pedalboard end or in the effects loop, as a second master volume setting even on multichannel amps.
