The ZVex Wooly Mammoth Vexter is the screen-printed production version of the Zvex Woolly Mammoth, a fuzz pedal made by ZVex. The Wooly Mammoth line is aimed at bass players as much as guitarists, and its defining control is the pinch knob, which shapes how much low end gets through the fuzz circuit1.
What it does
The Wooly Mammoth is a fuzz pedal, and the Vexter edition carries the same circuit as the hand-painted original in a screen-printed enclosure at a lower price. What sets it apart from most fuzzes is the pinch control: turning it changes the character of the low end, from a tighter, more gated feel to a full, woolly thickness1.
Premier Guitar, reviewing another fuzz pedal in 2021, referenced the pedal's reputation directly1:
"Fans of ZVEX's Wooly Mammoth might dig this setting since it sounds as if the pinch knob of the legendary pedal was maxe"1
Premier Guitar reviewer, 20211
That a reviewer reaches for the Wooly Mammoth's pinch knob as a point of comparison, and calls the pedal "legendary", gives a sense of how the pedal is regarded among players. Related pedals in the ZVex range include the ZVEX Woolly Mammoth 7, the ZVEX Germanium Woolly Mammoth, the ZVex Germanium Woolly Mammoth Mod, and the ZVEX Sylvia Massy Woolly Mammoth, a signature version1.
