Chris Squire

In this rundown, Chris's bass tech describes the unit as a 'Maestro fuzz box' at 15:56, although with controls such as brass volume, bass volume and sensitivity and the unusual layout of the knobs down the right hand side of the pedal it must be an original Brassmaster from the 60's

"Squire, who felt that certain effects were better matched with neck or bridge pickups, rewired his Rickenbacker with stereo outputs in the early ’70s. Onstage, he used a boatload of vintage effects, including Maestro Fuzz-Tone, TC Electronic Stereo Chorus Flanger, TC Nova Reverb, Boss OC-3 Super Octave, Mu-Tron III, and custom-made tremolo pedals. He played Moog Taurus bass pedals, eventually triggering samples from an E-Mu ESI2000 sampler."

At 16:18 a Mutron iii+ can clearly be seen on Chris's pedalboard.

In this rig rundown at 16:22, Chris's bass tech points out the delay and reverb pedals, both TC nova series, with the Delay in the middle between his Mutron iii and Nova reverb. His tech says "gradually over the years we've upgraded to those two, which he likes"

In the provided photo, Chris Squire is shown using a Marshall Model 1975 Supa Fuzz pedal during Yes' performance at the Crystal Palace Bowl in London, England, on September 2, 1972. The pedal's enclosure, identifiable by its more rounded edges, confirms it as a Supa Fuzz made between 1968 and 1972, as evidenced by the image provided. Photo taken by Michael Putland.
