Simple, lush analog chorus. Only one knob (Rate) and a depth switch. Kurt Cobain used it on Come As You Are and throughout Nirvana's catalog for that watery, underwater quality.
A direct comparison of the Big Muff and Fuzz Face circuits: how they work, how they respond to guitar volume and picking dynamics, and which one belongs in your signal chain.
Big Muff settings for every variant (Triangle, Ram's Head, Op-Amp, Russian, Nano) with sweet spots for shoegaze, rock, doom, and Gilmour tones.
