"indie pedal phenom, bass dirt guru, and Fuzzrocious Pedals founder"
The story: an indie, family-run pedal maker
Fuzzrocious was building pedals to order as early as 2011, when No Treble reported on the hand-made, hand-painted Terrordactyl, a fuzz with a bright violet LED powered by a Boss-style 9 volt adapter1. That built-to-order, hand-finished approach has remained the company's identity, and its range has since grown to span fuzz, distortion, overdrive, delay, reverb, filter and modulation pedals, many of them offered in multiple mod variants.
Known for fuzz: Gray Stache, 420 Fuzz and Big Fella
Fuzzrocious's catalog is anchored by fuzz. RockBoard's PedalPedia lists the Gray Stache, Cat Tail, Big Fella and Cat King among its pedals3, and the range reaches well beyond those:
Ryan Ratajski and the MXR connection
Founder Ryan Ratajski's reputation extends beyond his own brand. In 2015 MXR released the M85 Bass Distortion, a RAT-inspired bass distortion developed working closely with Ratajski24. For players comparing Fuzzrocious's own bass dirt pedals, such as the Rat Tail and Demon lines, the M85 is the mainstream-market expression of the same designer's approach to bass gain.
Power and support
Fuzzrocious pedals run on a 9 volt adapter, not a battery. The Terrordactyl, for example, is powered by a Boss-style 9 volt adapter1.
Plan for a 9V DC supply with a standard Boss-style plug. Fuzzrocious pedals such as the Terrordactyl are adapter-powered, so a battery is not an option1.
Later designs have added flexibility where the facts show it: the 420 Fuzz V2 carries a 9V/18V toggle switch5.
