This Gibson GA-20 is in better condition than any we’ve ever seen. This 1951 model features an earlier circuit with octal preamp tubes and produces a nice, crunchy midrange sound when overdriven. The power cord and electrolytic caps have been replaced, but otherwise, it remains stock. Miraculously, it still has the original wax coupling caps—though it works and sounds great, the next owner may want to consider replacing these if the amp is to see significant use. It even comes with the original cover, which looks like something straight out of an archaeological exhibit!
