The REVV Glenn Fricker Northern Mauler is an analog distortion pedal built as a signature collaboration between REVV and Glenn Fricker, one of the company's earliest supporters. It combines REVV's trademark high gain tones with a second circuit inspired by the Boss HM-2, the source of the "Swedish chainsaw" sound associated with metal's most aggressive genres. The two sounds can also be mixed together, letting the chainsaw character add cut and grit to a more traditional high gain tone1.
Fricker is known for his uncompromising, no-nonsense approach to audio production and his highly influential YouTube channel, which is where most players will know his name2.
What it does
The pedal runs two voicings in one box. One side delivers the high gain tone REVV is known for, and the other produces the Swedish chainsaw sound, a grimy, chaotic distortion drawn from the HM-2 circuit. according to RockBoard's PedalPedia, the chainsaw voice works on its own for extreme metal styles, or blended into a traditional high gain sound when a player wants extra cut and character1.
For players already familiar with REVV's distortion range, the Northern Mauler sits apart from pedals like the REVV G3 and REVV G4 by bringing the HM-2-inspired chainsaw voicing into the same pedal as a high gain circuit, rather than offering a single amp-style voicing1.
Power and specifications
The Northern Mauler is an analog circuit and runs on 9V DC, center negative, drawing 20 mA1. A standard isolated 9V supply covers it, and the modest current draw means it fits comfortably on a shared board supply setup.
REVV publishes an English manual for the Northern Mauler as a PDF on its site1.
