The S1 was Gibson's attempt to compete with Fender in the bolt on neck market. It debuted in 1975 and was discontinued in 1980. only 3100 were made.

​

It features 3 single coil pickups designed by Bill Lawrence that could be combined to get humbucker sounds. The chicken head rotary knob controls the pickup combinations:

​

• Neck + middle

• Middle + bridge

• All 3 together

• Neck + bridge out of phase

​

Overall, the neck is very comfortable and the tones are outstanding with loads of versatility.
