"Dave Dederer's simple, yet very effective, The Presidents of the United States rig started with a vintage Harmony H-802 guitar (bought for $40 bucks from PUSA drummer, Dave Thiele) that was loaded with two single-coil pickups and outfitted with two slider switches, and a single volume and tone knob. The guitar was strung up with "really heavy" Ernie Ball Slinky or GHS Boomer strings (.058, .046, .036.). "
