Gibson Amplifiers
Gibson's historic amplifiers define the era of American jazz and blues. The GA-series from the 1950s and 60s are collectible pieces with an inimitable tone.
About the brand
Gibson began manufacturing amplifiers in 1946, following Fender and other manufacturers who recognised the need to offer a complete guitar-amplifier system. The first GA (Guitar Amplifier) models of the 1940s and 50s used modest but musically satisfying circuit designs for the jazz and blues of the era.
The Gibson GA-20, GA-40 and GA-70 amplifiers from the 1950s and 60s are now collector's items sought for their warm, soft tones, ideal for jazz and blues of the golden era. Their dynamic response and natural compression make them particularly expressive for styles where feel and dynamics are central.
Gibson stopped manufacturing amplifiers in the 1970s, but in recent decades has relaunched some lines in collaboration with specialist manufacturers. Vintage Gibson amplifiers are now more valued as collectibles than as stage tools, but their history forms an integral part of the development of the American electric guitar sound.
