Chris Wolstenholme

Chris has been using this pedal since Muse's beginnigs, and he currently owns at least 3 of them. It is one of Chris's most used pedals, so many of his album and live bass sounds include the Big Muff.

Chris has been using a Wooly Mammoth since 2009. It is a strong gated fuzz that can sometimes resemble Matt Bellamy's Fuzz Factory. Chris uses this effect often, but the clearest example can be heard throughout "Guiding Light".

Chris has owned this rare and coveted bass synth pedal since the Origin of Symmetry era. It is responsible for many of his basslines, including "Time Is Running Out", "Plug In Baby", "Hysteria", "I Belong To You", etc.

"That is Chris's sound, like, if you hear pretty much anything off the last four records, this is what you're basically hearing...it is a distortion box; it's just something Chris stumbled on in a Japanese shop, and we basically got as many as we could." – Shane Goodwin (Chris' tech) on the Human Gear Animato

This rare and strange bass pedal is famously used by Chris Wolstenholme, and can be heard in combination with other effects on many songs such as "Uprising", "Plug In Baby" " and "City of Delusion".

Mix engineer Tommaso Colliva on recording Drones : "We use quite a few ZVex pedals, like the Mastotron and the Woolly Mammoth, because they have really crazy sounds, and while some of them are not controllable enough for a live scenario, they are really useful in the studio if you want very extreme sounds."
