Sustain
VR1The structural density engine. Rather than just adding raw volume, it pushes the internal op-amp stages into deep, interlocked diode compression. Turning it clockwise thickens the wave shape, melting individual notes and heavy chords into an unbroken, velvet sheet of infinite sustain.

Tone
VR2The classic passive frequency network. It beautifully cross-fades between a dark, woolly bass branch and a bright, glassy treble branch, allowing you to sweep through that legendary, deeply scooped mid-range profile to find the perfect mix placement.

Volume
VR3Governs the final master output level with a near-linear sweep. It packs massive clean output headroom, moving effortlessly from a balanced studio texture to an aggressive push that can completely hammer the input stage of a virtual tube amp.

Tone Bypass Switch
SW1Completely cuts the passive frequency network out of the signal path. This reroutes your guitar through a flatter, louder, and intensely focused lane, delivering an unscooped, raw fuzz profile with an immediate boost in mid-range authority and output volume.
