1978 Gibson S-1 used electric guitar. There were only about 3,000 of these guitars made between 1975 and 1980. The pickups are the original Bill Lawrence-designed single coils, and the wiring diagram is the much improved 2nd version (produced after 1977) that allows you to select (with the chicken head knob) neck only, center and bridge together in humbucking mode, all 3 pickups (very rare in any guitar) or neck and bridge out of phase for a great funk sound. Maple fretboard in good condition,. All frets ring out well, no fretting out or choking. Neck is straight and action is nice and low. Plays great. The pots are also original and the 2 way original "passing lane" switch works perfectly--in the up position the chicken head setting is activated, but in the down position it bypasses this to go to bridge only. Mahagony body, bolt-on 3 piece maple neck, original pick guard, knobs, switches, pickups, bridge (harmonica style), and Gibson stamped tuners are all in good condition. Case is not included.
