FACTOIDS & TRIVIA
Ampeg’s Gemini II was introduced in 1965. With almost
10 more watts of output and a 15 inch speaker it represented a more powerful
alternative to the Gemini I. Like its smaller sibling, the Gemini II is
a two channel amp with separate bass and treble controls and the added “Ultra
High” and “Repeat Percussion” effects. It is well suited for warm, clean
jazz tones and works best with humbucking pickups. The Gemini II remained
in Ampeg’s catalog until 1968 when it was superseded by the GV-15 Gemini
15. The amp shown here has a factory optional JBL speaker denoted by the “L”
suffix in the model number. Ampeg offered upgraded speakers at additional
cost from c. 1963-71 (JBL) and c. 1965-79 (Altec).
