Based on the Peavey amp, this preamp pedal is built to achieve that super saturated death metal guitar tone. Famously stacked with chainsaw tones to get that Slaughter of the Soul guitar tone. This is the high gain channel as a standalone preamp with some modifications. My modifications maintain the original character but are what consider "quality of life" upgrades as they just make it slightly easier to dial in. The active 3 band EQ makes it easy to dial in some killer tones but for some additional flexibility look inside to find DIP switches for the Bright (originally only available on the clean channel), hi/lo Gain, and Mid Shift controls just like the original. Running at ±15v inside means you'll have the same headroom you'd expect from the original design.
