Death is Gain - Low to Medium Gain Overdrive. This pedal is an articulate overdrive that is very responsive to pick attack and playing dynamics. The controls and circuit on this pedal are familiar, but the end result is anything but.
For starters, there is no mid-hump and the tone control is usable and musical at all settings. When cranked, the pedal has a rich, creamy tone that hits you in the gut with tight, full bass response. “Death is Gain” also works especially well for filling out single note passages and stacks well with other drives and boosts. Every guitar has a sweet spot that can be dialed in by the pedal’s gain control, where light picking will be clean and bell-like, while playing hard will produce overdriven bliss. From mild, dynamic gain to moderate crunch, “Death is Gain” will take you to tone heaven!
