Red Sun Music: Quadrafuzznia RS-4R Fuzz Pedal


This guy is an angry little beast, with slicked back hair and tight black jeans. The 4R hammers out classic high-gain op-amp fuzz tones without the fizz

It’s a Frankenstein’s monster of the best bits of a bunch of classic op-amp designs. We used a slow slew op-amp for rich thick overtones and asymmetric MOSFET clipping circuit bring home that toasty, luscious, high-gain fuzz. Things get pretty fat pretty quickly… But that fuzz control just seems to go on forever.

If this circuit were food, it’d be a chocolate mud cake made entirely of single malt whiskey and a lack of respect for authority.
