Here's a 70's Ampeg GU-12 1x12 all tube Combo Guitar Amplifier........This beast comes to us from Val McCallum noted L.A. Session Guitarist- currently touring with Jackson Browne. One of a few Ampeg Models that Keith Richards used on the Stones 'Exile on Main Street Album...basically the Ampeg version of the Fender Deluxe Reverb size wise, although it also has tremolo as well as reverb. Amp is in fantastic shape for its age. Non Original Speaker.
