This is a little snippet from an interview I conducted with Paul a few months ago:
GUITAR: New Ibanez PGM301, vintage Ibanez guitars
PICKUPS:
DiMarzio Tone Zone, DiMarzio PAF Classic
AMP: Marshall Vintage Modern
PEDALS:
Ibanez Tube Screamer, Fulltone OCD, Xotic Effects AC Booster, Fulltone Soul Bender. (Not all at once!)
Also, I often run my Marshall through a THD Hot Plate in my home studio. That way I can crank up the power tubes all the way, but keep the volume under control.
