The Airis Merciless Drive V2 is an updated version of the Canadian company’s hybrid and metal-oriented dirt box including a clean boost, a Rat-based ultra high gain distortion, and a boosted HM-2 EQ section, which can be all combined to taste.
The EQ section is particularly useful including a Low and two treble knobs: Byte (passive treble control delivering warm/smooth or sharp/bright tones) and High (an active circuit that can deliver chainsaw tones when maxed out.
The Blend control is also interesting, and it’s where the boost circuit is controlled: it mixes in boost+EQ with Rat distortion+EQ.
Needless to say, the amount of distortion is controlled via the Gain knob, while Volume sets the output.
