The Red Music Works website (Translated to English) tells us that the FD-1 is a 'fuzzy drive'. There's not much more other than it pays homage to the sounds of the 80s and 90s. I like to think of the Fury Drive as a cross between a TS and Fuzz Face but I'm guessing that knowledgeable circuit fiends will be able to deduce a more accurate reading once they peek the circuit board which I have included in this video. Regardless, this pedal is a seriously cool ride, especially with single coiled pickups, and I dig it a lot.
