Joe Perry of Aerosmith is overdubbing guitars at Swing House. There were two amps in the live room and one or sometimes two in the overdub room. We mic’d the live room so the ambience was consistent on every track. We also would take one of Joe’s 60’s Fuzz pedals and over a Neve Mic Pre. That was my favourite sound of Joe’s. He never settles, every song had it’s own signature.
