Why these settings

The Katana's Crunch channel emulates a JCM800-style voice, which is close to Billie Joe's cranked Plexi. Your Ibanez has higher-output humbuckers vs his P-90, so gain is pulled back from where a Les Paul Junior would need it (original amp was dimed). Mid pushed to 7 to replicate the Plexi's nasal bark that cuts through the mix. Bass at 4 keeps it tight — the original had big cab resonance, but the Katana 50's 12" speaker needs restraint to avoid mud.

PRO TIPPalm-mute aggressively on the low E during the verse power chords, then lift completely on the chorus — that dynamic shift is half of the Dookie punch. Pick hard and close to the bridge.
