REVV Northern Mauler

Although it’s white and made in peaceful Canada, the REVV Northern Mauler is a pedal for guitarists who are after the “Swedish Chainsaw” tone pioneered by metal acts with vicious names like Entombed, Dismember, Repugnant, Bloodbath, and Fuming Mouth, just to mention a few.

Designed in collaboration with (also) Canadian guitarists Glenn Fricker, involved with similarly gnarly ’90s bands Chaos and Dark Matter, the Norhern Mauler is a dual circuit gain pedal featuring an Amp (which is actually just an amp-voiced circuit, not a real power amp) and a Chainsaw circuit, the part of the pedal that adds that sought after sonic character and inspired by the BOSS HM-2.

The three top knobs on the right control the tone of the amp section and feature a traditional 3-way EQ, while the Bite and Growl knobs on the left fine-tune the quality of the chainsaw sound, controlling respectively the circuit’s treble and bass response.

The Blend control allows 100% Amp Circuit, 100% Chainsaw Circuit, or anything in between, while the Giv’r knob adjusts gain/saturation of both circuits at once.

REVV Northern Mauler, Builder’s Notes

Glenn Fricker is one of Revv’s earliest supporters & a lifelong opponent of stale, sterile guitar tone. Together, we set out to combine Revv’s trademark high gain tones with a sound inspired by the legendary HM-2*.

The Swedish chainsaw is the grimy, chaotic sound of metal’s most aggressive genres, but you can also mix it into your traditional high gain tone to add cut, character, & make your sound memorable.

One half of the Northern Mauler is a custom-tuned Revv high gain amp tone, & the other is our homage to the HM-2*. The blend knob gives you total control from 100% Amp Circuit, to 100% Chainsaw Circuit, & everything inbetween. Use a blend of the tones to transform your clean channel into a metal monster, boost your high gain amp with the Chainsaw Circuit, plug directly into a power amp, or use it with your recording interface & impulse responses.

Proudly Canadian, the Northern Mauler features a custom bear graphic, Glenn’s signature, & is designed to make it easy to inject some mayhem back into your metal.

“I’ve been wanting to mix the Swedish Chainsaw into modern metal tones for quite a while now. So I reached out to the guys at Revv, & after many months & many revisions, we’ve come up with The Northern Mauler. This combines the best of Revv’s wonderful super-tight metal tones with the out-of-control nastiness of the Chainsaw… & the results are better than I could have hoped for! We even kept the labeling simple so even the bass players could use it!” -Glenn Fricker, Spectre Media Group
