Ampeg Gemini series amps are well regarded by jazz guitarists for their rich, clean sound. This is not surprising since Ampeg founder, Everett Hull, was a jazz bassist that aimed his amplifiers squarely at jazz guitarists, bassists, and accordionists. The Gemini I, with its dual channels, and separate bass and treble controls, was an upgrade from the Reverberocket. In addition, the Gemini was equipped with an “Ultra High” feature which acted somewhat like a bright switch, and a “Repeat Percussion” feature which provided an echo effect of sorts. In fact, this amp was used predominantly by the “Manhattan Guitar Club” which was comprised of top New York metro area studio and performing jazz guitarists. This particular Gemini I is an example that has a deeper cabinet than most Gemini's. The Gemini I remained in the Ampeg line until 1972.
