What you get is:

• Multi instrument Preamp and Distortion with two gain channels, Independent Volumes, two simple and effective tone controls offering mid and low end tone shaping.

• One deceptively sophisticated Gain knob, pure clean to overdrive

• Two switchable channels: HI Gain and LO Gain which can be independently set for level output. Each channels gets its own LED knob indicating which channel is selected.

• LO gain setting ranges from crystal clear to overdrive while HI gain starts with rich clean harmonic sounds to full distortion.

• “Focus” adjusts the sub-harmonic frequencies to your bass signal, or to contour your over driven guitar sound.

• “Tone” for mid shaping the overdrives

• Internal input impedance switch for optimum matching

• Two foot switches: Hi/Lo Gain & True Bypass

• External DC Jack or 9v battery power (>80 hr typ. life)

• Pure analog circuitry: varying the external DC jack voltage (3V - 12Vdc max) will alter the harmonic characteristics of the Nucleus
