Ampeg's larger two-channel combo of the mid sixties and the step up from the Gemini I: about 30 watts RMS from a pair of 7868 output valves into a single 15-inch Jensen Concert speaker, with three 12AX7s, a 7199 phase inverter and a 6CG7 ahead of them and a solid-state rectifier. Each channel has its own volume, bass and treble, and each treble control carries an Ultra High switch that adds a very bright boost at the top of its travel. Ampeg's reverb, labelled Echo, and an opto-cell tremolo with speed and intensity controls share one channel. Everett Hull aimed the line at jazz players, so it stays clean and warm below about 10 o'clock; wound up it turns grimy, rich and raw with a fat, clear crunch, which is why it suits indie, alternative, blues-rock and roots music. It was built from 1965 to 1968 and it is the amp producer Mitch Easter lent R.E.M. on Murmur, where it replaced Peter Buck's broken Fender Twin Reverb on every song but Pilgrimage. The smaller 1x12 sibling is the Gemini I G-12.
