Gibson · amplifier

The Gibson GA-18 is a small vintage tube combo from the 1950s with a single 10-inch speaker and low wattage, prized for warm, woody breakup at low volume. Used by Bill Frisell in the studio, it delivers a touch-sensitive, slightly compressed vintage voice ideal for recording and ambient or roots playing where small-amp character is wanted.
