Why these settings

The Birdie MX-100 is an unrecognized unit, so knob parameters are mapped to universal British-voiced high-gain crunch standards with unverified controls set to null. The dual humbuckers on your Washburn WI24 provide the thick, driving output required for Billie Joe's heavy bridge-pickup attack without needing an external boost. Keep the gain around 7 to maintain articulation and bite on the descending power chords without descending into muddy saturation.

PRO TIPTune your guitar down a half-step (Eb standard: Eb-Ab-Db-Gb-Bb-Eb) and clamp down your right-hand palm aggressively between the chord hits to achieve the signature dead-stop silence between each chord.
