The WM7 is an impossibly gigantic-sounding fuzz box that works equally well with guitar or bass. The EQ knob of the original has been replaced by a full Marshall-style three-band EQ for supreme control. Now, guitar players can dial in a heavy thump or fantastic lead tone. The second footswitch removes all equalization from the circuit completely, resulting in a mids-rich sound that lays waste to any amp in its path. A handy second volume knob keeps the levels of both modes in check for seamless switching mid-song. The Pinch controls the pulse width of the fuzz, letting you dial in open, sustaining fuzztones or ripping, gated sounds that stay quiet in high gain settings. Two painted transistors act as the pedal's secret sauce and can be seen through the clear porthole on the face. The ZVEX Woolly Mammoth 7 features awesome hand-painted graphics and come with a lifetime warranty, and are hand-made one at a time in Minnesota, USA.
