Product information "Subdecay Variac Overdrive"

With tones ranging from AC/DC, early Van Halen, Judas Priest to Tom Morello and even 80s hair sounds, the Variac Overdrive is more than another amp in a box. It places an entire era of rock tone at your feet. It’s based on tests of individual tube circuits, careful listening to some of our favorite rock and old school metal, and the topology of amplifiers the artists actually used.


  • Preamp - controls the preamp gain

  • Pentodes - controls the power amp gain

  • Tone Stack - The treble and bass knobs control the frequency response.

  • Cathodyne / LTP switch - Two common tube amp phase inverters. Cathodyne setting has more bass and a looser response. LTP (long tail pair) for tightening up the low end and a more focused sound. This switch has more influence with more pentodes gain. In general for smaller amps you’ll want to set this switch to cathodyne, and LTP for amps with two or more speakers.

  • Volume - makes the effect louder… or quieter if you are in to that kind of thing.

For a deeper explanation check out the “Control Interactivity” tab.
