Sylvia Massy & ZVEX Unveil Limited Woolly Mammoth Pedal: Handcrafted Fuzz with Crushing Low End

ZVEX Sylvia Massy Woolly Mammoth

ZVEX Effects has teamed up with audio wizard Syvia Massy to introduce a new, limited edition version of their Woolly Mammoth fuzz pedal. The Sylvia Massy Woolly Mammoth is described as a “monstrous fuzz pedal that delivers crushing low end for bassists while also blistering on guitar.”

Central to the pedal’s design is its use of hand-selected and tested new-old-stock 2N2222A transistors. Massy, who is acclaimed for producing artists from Tool to Prince, also created the artwork, which is UV-printed onto the chassis. Similar to the original Woolly Mammoth circuit, the Massy version has Output, EQ, Pinch, and Wool controls for dialing in your grit.

Hear the pedal in this quick video from ZVEX:

The ZVEX + Sylvia Massy Special Edition Woolly Mammoth pedal is limited to 60 units, each hand-assembled and hand-numbered. They’re available now for $399.
