Gibson GA-6 Model Tube Amplifier (1956), made in Kalamazoo, Michigan, serial # 24728, mottled grey fabric finish.

This collector-grade GA-6 is in a spectacularly preserved, close to near-mint state with minimal signs of use and remains beautifully original. In the middle years of the 1950s the GA-6 was Gibson's mid-line amplifier offering, intended to directly compete with the classic widepanel 5C3 Fender Deluxe, which in fact, the circuit of the GA-6 resembles quite a bit. The GA-6 has long been referred to as the "poor man's tweed Deluxe", although at the time it was not actually less expensive!

Much like the 5C3 Deluxe, the GA-6 sports two channels, each with a volume control and a master tone, alongside three instrument and one mic inputs. This amp's outer textured cloth "oatmeal" or "poodle" covering is in immaculate shape, as well as the grille cloth. The faceplate is likewise completely unscathed, with all the stenciled graphics intact and no visible scratches or wear. The original handle is still in great shape and the amp comes with the original brown cloth cover as well as the original instruction manual.

Electrically, the amp is nicely original, save for some routine maintenance. Both power and output transformers are original to the amp and marked GA-20 and Z-3560/220-631 respectively. The original Jensen P12R, marked 220-632 (32nd week of 1956) is in fantastic shape. The Centralab pots date to early '56 (304-605). The amp has received typical maintenance to ensure reliable and safe operation for years to come, including the replacement of all electrolytic capacitors and any coupling capacitors that are too far degraded. All sockets, pots and jacks have been cleaned and the power tubes have been biased to spec. The amp also has been outfitted with a 3-prong grounded power cord. It sports Sylvania 5Y3 rectifier and 6V6GT power tubes, a NOS RCA 6SL7 and a GE 12AY7.

A relatively powerful and rich Gibson amp for its size, the GA-6 is one of Kalamazoo's best offerings from this period. It makes a great recording amp with a sonic kinship to the Fender Deluxe with the highest frequencies smoothed out a bit, sweet and warm with gorgeous musical distortion when pushed. This is truly one of the most stunning and well-preserved 1950s Gibson amps we've ever seen. Excellent + Condition.
