The Gibson GA-9 is a small combo from the mid-1950s, offering around 9 watts from a pair of 6V6 output tubes. Intended for the student and home practice market, it nonetheless produces warm, characterful tones suited to jazz, blues, and early rock and roll. Its simple circuit is transparent and touch-sensitive, responding well to pick attack and guitar volume control.
