Variac

The SubDecay Variac captures the spirit of cranked tube amps in a flexible, stage-ready format. Inspired by the tones of Angus Young, Eddie Van Halen, Judas Priest’s classic era, and Tom Morello, it delivers the punch, articulation, and harmonic richness that defined decades of rock guitar. Designed to emulate a hot-rodded tube preamp and power amp—with selectable phase inverter voicings—the Variac responds with singing sustain, huge chords, and effortless pinch harmonics. Controls interact naturally, while supply voltage (7.5–18VDC) subtly shapes headroom, dynamics, and feel—like adjusting the behavior of a real amp. From classic hard rock crunch to soaring ’80s drive, the SubDecay Variac brings iconic amplifier character to any volume level.
