Here is an awesome old 1948 Gibson GA-30 guitar amplifier. Looks like it has the original tubes. This amp has had a new handle added as well as the grill cloth was replaced at some point. I believe the speakers were replaced also. This amp currently works as is. Turns on and plays. The volume and tone knobs work properly. Now this being a 75+ year old amp, I will say that it will benefit from having an amp tech look over it and make sure all of the components are working properly. Right now it sounds pretty good with some slight hum when turned up loud. Has the original 2-prong cord that really should be replaced for safety also. With all that being said, this is a really solid 1948 Gibson GA-30 that has been used and taken care of for the last 75+ years. Should have a lot of life left if the new owner continues with proper maintenance.
Up for sale, a 1963 Gibson GA-30RVT Invader in great condition, complete with the original footswitch. Please examine the pictures closely for a complete description. This GA-30RVT has a complete vintage tube set and a pair of original Jensen speakers-a 12″ C12R ceramic magnet driver and a 10″ P10R alnico magnet speaker. This amp is surprisingly quiet and sounds great. Cleans are clear and bold. The Reverb is unique and acts as a volume control as opposed to a wet/dry mix. This allows the effect to be heard with the amp volume otherwise at zero (a particularly ethereal sound), and also causes the reverb to have its own natural overdrive characteristics when you crank it. The Tremolo is particularly dimensional and deep with a strong throbbing quality. The circuit is original and professionally serviced only as strictly necessary, with new electrolytic caps and a modern three-prong power cable. All of the original transformers are intact and all of the pots are original as well. This model has 8 Tubes and include a matched pair of Westinghouse 7591 power tubes, a Amperex Bugle Boy rectifier, and original RCA-branded valves in the preamp. The amp schematic appears to be identical to the early and coveted Epiphone EA-12 RVT Futura. The speakers are both original to the amp. In addition, there is a switchable external jack that cuts off the connection to the output transformer, allowing you to easily use this as a stand alone speaker cabinet. The cabinet construction is impressive and the overall unit is unbelievably clean. The amp features its original smooth brown covering and two-tone grillcloth, with a large Gibson badge on the face, almost pristine graphics on the aluminum faceplate, and a full complement of reflector cap knobs. The original (hard-wired) two-button footswitch is included.
