Live and in the studio, Jones uses a blend of amps. Two favorites are a 1976 Marshall Super Bass and a Diezel VH-4 “blueface.” On the latter, he never switches out of the ultra-high-output third channel. During the recording of 2001’s Lateralus, he reportedly experimented with a vintage Sunn lead head, too, and for 2006’s 10,000 Days he blended his Super Bass and Diezel with a Bogner Uberschall and a Riveria Knucklehead. Jones drives all his amps hard to achieve his responsive tone. He also uses Mesa Boogie Dual Rectifiers and Marshall and Mesa cabs.

Quote: Guitar Player Magazine: Did you stick with the same gear to maintain that continuity? George Lynch: No, there was a whole bunch of gear. At this point the basics of my rig are my Randall Lynch Boxes, my ’68 plexi Marshall, and my #6 Soldano built in 1987 that was on the very first Lynch Mob record. For the bulk of the rhythms on this record, I used Engl Powerballs through old Hiwatt cabinets. I used some Rivera amps occasionally. I used my plexi for solos, my ’65 Super Reverb for a lot of the cleaner stuff, and one of my secret weapons—my ’70s WEM Dominator with a 15" speaker. It’s a bass amp that’s great for real chimey AC30 sounds.
