This is a very collectible 1965 Ampeg G-15 Gemini II, a 2-Channel 30-Watt 1x15" Guitar Combo made from 1965 - 1968. Its Blue Tolex is near perfect all over. This is a great jazz amp and has a nice warm tone. The amp is in fabulous condition for the pickiest collector. Both of the channels have a strong output and features a large 15" speaker for great bass response. The amps natural tone is very dark and perfect to plug in any electric guitar and get a fantastic jazz tone. Attached is the optional Ampeg Dolly upgrade that is just attached with one screw in the middle. It comes complete w/its matching Blue Tolex amp cover. Truly a wonderful user friendly investment.
