ZVEX Fuzz Probe Vexter

The fuzz probe is something like a fuzz crossed with a theremin. The mental sounds generated by this pedal can be controlled with your foot and its interaction with the copper antenna on the top of the unit. Very wild indeed.
The Vexter series is the same as the original but silkscreened instead of handpainted which saves you a lot of money if you don't need the fancy paintjob.
