Discrete, analog circuit (no ICs, op-amps in audio path);
30dB boost, 5 N.O.S. Germanium transistors;
Full size, through-hole components;
True bypass; Active Bass and Treble controls;
Mid Shift switch tailors mid/high frequency response;
Gain Shift adjusts low-end response when Gain knob is set above minimum;
Operates on 9V battery or standard 9V power supply;
Internal circuitry doubles supply voltage for high headroom.
