"Additional pedals include a Boss CS-2 Sustainer, MXR Dyna Comp, Iba- nez CP9 Compressor-Limiter, Boss Hyperfuzz, Electro-Harmonix Big Muff, two Chandler Industries Tube Drivers and three Boss Graphic Equalizers. He also operates several master volume pedals: one for his 4x12 cabinets, another one for his rotating speakers, another for his voice box and a speed control for the doppolas." - [Phil Taylor, David Gilmour's guitar tech.](http://www.pink-floyd.org/artint/dagear.htm)more
According to Gossard's guitar tech, "We use different pedals to achieve different amounts of distortion and overdrive: a DOD graphic eq pedal that boosts the signal and drives the amps' preamp sections harder, a Boss Hyperfuzz…" Full article [here.](http://www.guitarfxdepot.com/rigs/stone-gossard-pearl-jam-guitar-rig/)more
Picture taken at the mondo generator show in Cagliari on 20/09/2016, this was nick's pedalboard, featuring a boss hyperfuzz 2 constantly on duty, and a Dr.No Black Magic Bass Distortion only to boost some solos and general feedback. On the right, a classic boss chromatic tuner with an unmistakable DWARVES sticker on itmore
Highly Desired for a reason, it has 2 very usable, very different fuzz tones, and a clean boost. Most likely you will be tempted to crank the gain, but you may find that lower gain can actually sound heavier. Highly recommended.
Note- The Behringer clone is incredibly comparable, and is a cheap, useful buy if you want to know if you want to commit to the real deal, it sold me.
the FZ-2 is a univox superfuzz copy... it differs in the last make-ups tage after all the fuzz and octave happens. Boss used an opamp instead of another transistor and they added a useful treble and bass tonestack there. It has the 2 settigns for flat and mid boost of the superfuzz and it also has a boost setting that disengages the discrete transistor section leaving only the makeup stage that has so much more gain than the univox's transistor stage that it makes an excellent boost/EQ. I enve ropened my hyperfuzz when I had it so I am unsure if it had Panasonic transistors for the fuzz like in the univox I owned, but they're unremarkable devices so it probably doesn't matter what's in this circuit. Because of the different output section this pedal plays well into wah and other effects whereas my superfuzz was finnicky. I owned this prior to the superfuzz and didn't even know it did octave when I bought it. I didn't bond with this type of fuzz at the time but I've since become a fan and wish I still had the FZ2. The Behringer superfuzz is a cheaply made copy.
I use this amazing pedal to recreate the 60's psychedelic octavia fuzz tones. Sometimes I use an overdrive or distortion pedal to boost the gain of the fuzz, that increase the colors of the sound. Very usefull to play stoner rock, alt rock or 60's stuff.
