Gibson GSS100 Amp Brochure, Super Rare! 1966

Here is an original 1966 Gibson GSS-100 amplifier brochure, promoting “The New Concept in Sound Projection.” This striking full-color piece highlights Gibson’s ambitious 100-watt solid-state design, featuring bold mid-’60s graphics, specs, and marketing that emphasized projection “wider, deeper, farther.” The brochure details unique features such as stereo reverb, tone contouring, and solid-state circuitry—Gibson’s forward-looking but short-lived foray into transistorized amplification.

This example is in excellent condition with crisp pages and vibrant colors, showing only minimal handling wear. Extremely rare, as few examples of these brochures survived Gibson’s brief solid-state experiment, it is a prime collectible for Gibson historians and vintage amplifier enthusiasts.
