In the mid-'50s, the electric guitar was taking off! Everyone knows that Gibson was a leader in the development of the electric guitar, but even though their amplifiers produce fantastic tone, Gibson amps have never commanded the high values of comparable vintage brands. Because of that, a good Gibson amp can deliver authentic vintage tone and mojo at a much more accessible price.
The GA-6 was essentially Gibson's answer to the tweed Deluxe. By 1956, it featured a 12-watt design with a 12" Jensen speaker. Its preamp is driven by one 12AY7 and one 6SL7, and its power section features two 6V6s and a 5Y3 rectifier tube. With four inputs and two channels (three for the instrument channel, one for the microphone channel), the GA-6 delivers classic American tone.
This c. 1956 Gibson GA-6 is a great example of this classic design. Its original Jensen P10R Alnico speaker was re-coned in 2019, and its filter caps have been replaced and properly serviced. It also sports a safe three-prong power cord for modern use. Other than that, it appears to be all original, down to its leather handle which has deteriorated (but we'll leave it up to the next owner to replace it). Nothing looks as cool as this mottled gray-brown covering!
