U.K First
The Little Acid Fuzz V2 from Frost Giant Electronics is an exact recreation of the notorious 1970s one-knob Op-Amp fuzz commonly known as the Little Big Muff. Famous for its unrelenting, glitch edged aggression, this circuit has powered countless records thanks to its raw, abrasive character and unmistakable bite.
Over the years, even original manufacturers subtly altered this design. Frost Giant went back to the source, tracing an original ’70s Op-Amp unit component-for-component, to restore the circuit to its true form. The result is a fuzz that delivers snarling saturation, compressed grind, and that unmistakable sputtering edge players love, without the fragility or inconsistency of vintage units.
The V2 update expands the original concept without compromising its identity. A Tone Bypass switch unleashes extra heft and output for a more direct, unfiltered fuzz assault, while the newly added Mids control lets you dial in cutting frequencies that help the pedal punch through dense mixes - something the original circuit could only dream of.
Despite its minimal external controls, an internal tone trimmer allows fine tuning to suit different rigs, amps, and guitars, ensuring maximum usability from a deceptively simple layout.
The Little Acid Fuzz V2 is unapologetically loud, aggressive, and unstable in all the right ways. A classic Op-Amp fuzz energy, refined just enough to be stage, and studio-ready.
