One of the most unique offerings put up by the company in the 1960s, the Gibson GA-79 RVT Amp offers a vanguard design and enveloping stereo sound in one package. Designed with independent preamps in a dual 10" speaker design, the GA-79 is capable of up to 30 watts of power and comes packing odd-bird components like Jensen P10Q speakers and 6BQ5 tubes in the output stage. The real star of the show here is the ability to kick in three-dimensional stereo reverb and tremolo and lather up waves of sonic wash.
