ZVEX Woolly Mammoth – ZVEX EFFECTS

Description:
Sensitive and touchy, This 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

In our continuing effort to be friendly towards the earth, the universe and it’s inhabitants; no animals were harmed during the making of this pedal.

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!

    1. Just finished building it and it is backward. Just need to cut the trace between lugs 2 & 3 and solder a jumper from lug 2 to 1.

      1. where it does what it say?

        you say that, you have to “…cut the trace Between lugs 2 & 3 and solder a jumper from lug 2 to 1…” for the potentiometer of the “wool”?

        thank you very much

  1. Saya butuh refetemsi u memperbaiki rangkaian VS motor control (electric motor 3 phase yg di control speed melalui kumparan medan elektromagnetic eksternal. Ada yang bisa bantu.
    Thanks

    Leo

  2. Are u saying the directions for the “mamoth ” are incorrect? Please elaborate as I’m getting ready to build it ….thanks mark
