“Feast on Fuzz”
Each Mode isn't a tone shift laid over one fixed circuit — it reprograms the transistor forward betas, diode clipping branches, and passive tone-stack values of all four gain stages to match that era's real component spread. Ram's Head keeps the fullest low end of the American lineage; the Pi opens into a brighter, more mid-forward voice; Green Russian clamps down into the darkest, most compressed, tightest-bottomed version of the circuit.
A modeled Tube Screamer-style overdrive lives inside the same signal path, with its own Drive, Tone, and Level. Route it before the Muff to push a tighter, more focused signal into the fuzz's clipping stages, or after it for a saturated, boosted output — the classic two-pedal stack, built into one plugin. It also stands on its own: switch the Muff off and the overdrive alone covers everything from a clean mid-boost to a singing, saturated drive.
What do the knobs actually do?
Sets the gain feeding the first clip stage. Low settings stay closer to a raw, spitty push; higher settings drive the cascaded transistor stages into the Muff's signature dense, singing sustain.
The classic passive Big Muff tone network, scooped by design. Sweeps between a dark, woolly low end and a bright, buzzy top end, with the exact crossover point shifting per Mode to match each era's real tone-stack values.
A peaking mid-band control layered after the tone stack to push back against the Muff's inherent scoop. At zero it's fully vintage-scooped; turning it up fills in the mid-range so the fuzz cuts through a busy mix instead of disappearing behind it.
Final output level from the modeled volume pot, with enough headroom to sit at unity or shove the next stage into its own saturation.
Switches the whole modeled circuit between three historic Big Muff eras: Ram's Head, Big Muff Pi, and Green Russian. Each carries its own transistor, diode, and tone-stack values rather than a shared core with a different EQ curve.
A separately modeled Tube Screamer-style boost with its own gain, tone, and output stage, switchable before or after the Muff. Enable it to stack a second, distinct drive circuit into the same signal chain.
