The four knobs already provide three stages of gain (Volume, Level and Gain, which is the internal amp), which, by themselves, can concoct a wide range of ways to push your amp into overdrive and distortion, with the Bias control there to help fine-tune the high-end.
Under the hood, a host of DIP switches let you adjust several other options like full stack/half stack (with the former adding an extra 40dbs of gain with soft clipping), linear/nonlinear DC feedback (providing slightly different gain and frequency response), and true/buffered bypass.
Hear how this pedal sounds in Demos in the Dark video, below.
Single stage ultra high gain JFET booster/preamp offering clean amplification to overdrive and warm distortion to murder-your-face amplification.
Two amplifier topologies available via PCB mounted switch. “Half Stack” and “Full Stack”; the latter injects a pair of matched current sources creating an additional +40dB of gain with softer clipping.
Two modes of negative DC feedback for each topology via PCB switch; ‘linear’ and ‘nonlinear’ offering slightly different gain and frequency response characteristics.
