Sometimes dismissed as a Hendrix clone, Frank Marino’s Grateful Dead-meets-jazz improvisations featured some serious speed. His wild solos influenced Paul Gilbert, Zakk Wylde and Joe Bonamassa, and his singing SG tone was as significant as his licks. It still has its original PAFs and vibrola tailpiece, but had to be retired from touring by 2007 for its increasing fragility. Marino tried putting Strat pickups in an SG, but removing the necessary wood made the neck fall off.
