Zvex USA Woolly Mammoth Effects Pedal (as new)

Product code: bstuwzvexwoolly

Sensitive and touchy, The Z.Vex USA Wooly Mammoth bass fuzz has tremendous bottom end and a beautiful harmonic structure that sounds blistering with a guitar too. The harmonic structure can be radically altered using the PINCH knob. It adjusts the pulse width of the waveform. In the leftmost position, the waveshape is quite symmetrical which produces a smooth creamy sound. Turning it up slightly introduces lovely intermodulation distortion.

    Sensitive and touchy, The Z.Vex USA Wooly Mammoth bass fuzz has tremendous bottom end and a beautiful harmonic structure that sounds blistering with a guitar too.
    The harmonic structure can be radically altered using the PINCH knob. It adjusts the pulse width of the waveform. In the leftmost position, the waveshape is quite symmetrical which produces a smooth creamy sound. Turning it up slightly introduces lovely intermodulation distortion. Turning it clockwise narrows the waveshape into asymmetrical pulses, making the tone reedier and brassier. This also introduces an unusually smooth gating action, which gives you an absolutely eerie silence between notes.

    At most settings you will notice that low frequency pressure is preserved. This circuit has a frequency response that continues several octaves below audibility. The subs will knock everything off of your amps, so put the the bottles on the floor. No kidding.
    The WOOL knob adjusts the amount of fur around the note. The EQ knob tilts the spectral response, turning to the left adds lows and softens the highs. Turning to the right adds highs, then mids, and finally reduces lows. the OUT knob Is designed for smooth repeatable level settings
    Oh, and the circuit designed by Chuck Zwicky draws less than one-half of a milliampere 0.0004 amps, typical. That is less than one-hundredth the current consumption of most commercial pedals, giving this pedal about as high a battery life as you can find anywhere. In fact, if you use an alkaline battery and always unplug the input cord between sessions, you may never have to change it at all.
