~1966 Ampeg GS-15-R Gemini VI Blue Diamond

Offered for sale;

Used c1966 Ampeg GS-15-R Gemini VI serial number 022842.

This amp is in very good condition, fully functional. The speaker is non-original, cosmetically there are nicks and marks around the cabinet and the faceplate shows some age related tarnishing.

The Gemini VI GS-15-R was a continued evolution in the Gemini Series. It is a single channel version of the Gemini II, with tremolo and echo, also featuring a fixed-bias power section that bumped up the output to 30 watts. Originally intended for the accordion and guitar, it found popularity among guitarists.

The amp has some interesting features, there is a "click" stop past the usual maximum point on the treble control. This was called an "Ultra High Switch" it serves as a "bright" switch. Likewise, the tremolo intensity pot has a "click stop" that activates a "repeat percussion" feature that was supposed to offer an echo repeat sound, it actually turns the volume completely on and off rather than just modulating it up and down.

Like other Gemini amps, this GS-15-R features the famed Baxandall type treble and bass circuits that both "boost" and "cut", bass and treble, not just "cut". The cabinet is divided between the power section and the speaker section, allowing the speaker portion to be fine-tuned with a smaller "port" type of opening in the back panel, while still allowing the upper "power section" to be more open and provide better cooling. The traditional Blue Diamond Tolex covering and brown grille complete the classic Ampeg styling.

This amp sounds absolutely great, like a mid-sixties Ampeg should.
