RECOMMENDED — not currently owned; with this pedal, switch amp to Clean channel and set amp gain to 2
The MG15R's Overdrive channel provides the primary clipping to substitute for Dave Grohl's cranked ToneMaster and Rat combo. Mids are boosted to 7 to capture the signature 90s post-grunge punch through the 8-inch speaker while bass is kept at 5 to prevent low-end flub. Treble is dialed to 6 to preserve sharp attack without turning harsh on the ceramic Jackson humbucker.
