Designed for bass, a favorite for guitar, this incredibly sub-frequency-preserving unit will hold on to the lowest lows like no fuzz ever heard before. It features a gentle gate for silencing your instrument between notes or phrases, and has an EQ control that smoothly selects between more bass and more treble.

Vexter Pedals

Vexter Series pedals are lower priced, featuring silk-screened art. The parts inside Vexter pedals are identical to the hand painted models.


  • OUTPUT: Designed for smooth repeatable level settings.
  • EQ: Tilts the spectral responce, turning to the left adds lows and softens the highs, then mids, and finally reduces lows.
  • PINCH: The harmonic structure can be controlled with this knob. It adjusts the pulse width of the waveform.
  • WOOL: Adjusts the amount of fur around the note.


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 clock- wise 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 circut has a frequency response that continues several octaves below audibility. The subs will knock every- thing off your amps, so put the bottles on the floor. No kidding.

Oh! And the circut 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 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.


All Z.Vex pedals use 9V DC power supply with (–) polarity on the middle pin (typical Boss power supply). Using the incorrect supply may damage your pedal.
