01Tube Screamer (TS9 or clone)
RECOMMENDED — not currently owned. Use ONLY for chorus sections to add grit; bypass for verses. Set amp to Clean channel when using this pedal.
02Digital Delay (Boss DD-3 or similar)
RECOMMENDED — not currently owned. Delay time around 350-400ms, subtle mix for ambient spaciousness.
The MG30CFX is solid-state with a naturally brighter, less warm voicing than the original Fender Twin—compensate by using the Clean channel with mids pushed to 7 (vs typical 6) and treble held at 6 to avoid harshness. Your SC-Custom II humbuckers are hotter than Rzeznik's piezo acoustic, so rolling volume to 8 and tone to 7 softens the attack and mimics that open, jangly acoustic-electric quality. Gain at 3 gives just enough edge without obscuring the droning open-string character.
