The story is, the black box was built by Warren Ellis’ brother Murray from old radio parts, in an attempt to make an Octavia pedal, but coming out as something weird and evil sounding: The Muzz effect. The Muzz effect itself is based on a 1970s Octavia circuit, with some departures from the vintage design, adding an extra mean and evil character to the already excentric sounds and behaviors of the old classic. The Muzzbomb can be used in much of the same applications as an Octavia. Basically it’s an octave-up fuzz effect with some ring modulation going on too.. The Muzz likes to have a fuzz or an overdrive in front of it as well as after. It’s a tool for experimentation, and the only rule is “no rules”. Warren Ellis generally uses a boutique overdrive before the Muzz, which gives a fatter sound. Putting a dirt pedal after the Muzzbox will usually emphasize the octave-up effect.
