Why these settings

The Champion 20 lacks physical Middle and Presence knobs, so select the British Crunch voice to replicate Billie Joe's modded Marshall midrange push. Because your Squier has a single-coil bridge pickup compared to his bridge humbucker, keep Bass at 6 to add body and roll the guitar tone knob slightly down to tame harsh single-coil bite without losing punk crunch. No pedals are needed since the amp's British voice provides the required preamp drive.

PRO TIPHard downward rest-strokes near the bridge saddles with firm left-hand muting between the chord stabs are essential to recreate the choppy, gated stop-start rhythm of the live intro.
