The GreyFly is a hand-built pedal from Fuzzrocious Pedals, made in collaboration with Electro-Faustus. It is a noise generator that uses a set of springs, combined with the circuit of the Fuzzrocious Gray Stache fuzz pedal. Gearnews described it as "an intriguing mix of noise and fuzz retailing at a boutique price," with an RRP of USD $300 at its June 2016 release1.
What it does
The GreyFly is a curious amalgamation of two designs: the Electro-Faustus Blackfly, a noise generator that uses springs, and the Fuzzrocious Gray Stache fuzz. The springs are mounted on the top of the pedal and are attached to an internal piezo pickup1.
You get to scrape and flick the springs, and this can generate all sorts of odd noises. Then you can kick in the Gray Stache fuzz to get them fuzzed out and angry1.
The springs can be driven just by the plucking of them, or you can feed them into the fuzz circuit and drive them through it. In practice that means the pedal can act as a standalone spring noise generator, or as a fuzzed noise source, depending on how you set it1.
The mid control
The GreyFly also sports an adjustable mid-frequency control for the fuzz, to make it stand out a bit better, which Gearnews suggested might help in a band scenario1. The Gray Stache circuit it is based on carries the same idea: MusicRadar's reviewer Alex Lynham noted that "there's also a mids control" on the Gray Stache2.
The Gray Stache circuit
The fuzz at the heart of the GreyFly comes from the Fuzzrocious Gray Stache, which the maker describes as based upon the GGG-tuned and Civil War versions of a muff fuzz. according to RockBoard's PedalPedia's product page, dialing back the sustain achieves more of an overdrive sound, and the design aims at "creating one versatile guitar AND bass-friendly monster!"3.
MusicRadar's verdict on the Gray Stache itself was short on one point: "Pricey."2
Who it is for
Gearnews' overall judgement was that the GreyFly is a neat idea, just one best left to the more adventurous musician or noise terrorist, not for conservative players1. Players after a more conventional gate or suppressor will find different tools on the Noise Gate Pedals page.
