Why these settings

The NUX Mighty 20 MKII's Crunch/OD1 model delivers the tight mid-forward punch this J-pop rock tone requires. Mid pushed to 7 preserves note definition in the fast palm-muted riff sections that define this song. Gain at 6 provides enough saturation for the energetic feel without washing out the chord clarity. Reverb kept low at 2 since the studio recording is relatively dry with tight production.

PRO TIPThe signature riff relies heavily on precise palm muting - keep your picking hand anchored close to the bridge and use downstrokes on the power chord hits with quick muted scratches (the 'x' notes in the tab) to nail that driving J-rock rhythm feel.
