The ZVEX Woolly Mammoth is a sensitive and touchy. This bass fuzz has tremendous bottom end and a beautiful harmonic structure that sounds blistering with a guitar too.
TAMING THE BEAST
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 your amps, so put the bottles on the floor. No kidding. Oh! And the circuit 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 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. In a continuing effort to be friendly towards the earth, the universe and it’s inhabitants; no animals were harmed during the making of this pedal.
