The Northern Mauler is the result of a colloboration between Revv Amplification and Canadian metal engineer / YouTuber, Glenn Fricker. The 2-in-1 distortion pedal features Revv's take on the iconic HM-2 pedal and an all-new high gain amp-voiced circuit, serving up a filthy, over the top sonic assualt! 

Taking inspiration from the iconic "chainsaw" sound of Swedish death metal and American hardcore music, the Northern Mauler combines sonic elements of the HM-2 with a unique Revv high gain tone, custom tuned for Glenn Fricker. Optimised for use with both clean and high gain amps, the Northern Mauler also works seamlessly with power amps and recording interfaces with impulse responses.

Not for the faint of heart - you have been warned!
