KSR Gemini 100 Guitar Head Black Snakeskin

The KSR Gemini 100 is a modern 2-channel 100-watt tube head that delivers a massive range of tones, from crystalline cleans to punishing high-gain saturation. With fully programmable channel modes, extensive voicing options, MIDI control, and a transparent effects loop, the Gemini 100 is one of the most versatile tube heads on the market. Its programmable architecture allows each channel to store multiple voicings, with up to 8 clean variations and 96 permutations on the lead channel, making it a true chameleon for stage and studio alike.

This example is in excellent condition, finished in black snakeskin tolex, with only minimal signs of handling. It is serial number 01-20091 and includes the original footswitch.
