Up for sale, a 1954 Gibson GA-20 in excellent condition and in perfect working order. Featuring original two-tone cosmetics, a Jensen P12R speaker, and a professionally serviced circuit, this GA-20 is the perfect mid-size combo from the golden age of tube amplification. In many ways analogous to Fender’s narrow panel tweed amps of the same era, the GA-20 features a four input design with a 6V6 power tube pair, 5Y3GT rectifier, and dual triode (12AX7, etc) tubes in the preamp. Offering distinctly different voicings between the single Microphone input and the three Instrument inputs, the GA-20 is at its most aggressive via the Mic channel. While this input does offer a modicum of clean headroom, it quickly overdrives with a sizzling, chewy sound that’s extremely smooth. The Tone control has an absolutely massive sweep, actually adding a bit more gain when turned up. Maxing out both Volume and Tone knobs yields a ripping, cutting sound that interacts equally well with single coils and humbuckers. The Instrument inputs have more range in the clean signal, with a full-bodied and sweet sound that works well with a host of effects pedals. Turning down the Tone knob on this channel and pushing the Volume can achieve a very nice bark and a spitty quality almost akin to certain fuzz boxes, depending on the guitar being used, and once again diming everything out delivers plenty of richness and roar. The point-to-point circuit has been professionally serviced and thoroughly recapped with premium tubular signal caps in the preamp and F&T power supply caps. The output transformer has been replaced with a vintage-accurate Mercury Magnetics ToneClone GA20-O, mounted to the speaker frame, while the original power transformer is intact, mounted to the back of the chassis. The speaker is the original Jensen P12R alnico magnet driver which has a dark blue/green frame. The speaker has been recently professionally reconed, and the date code on the edge of the frame is from the 9th week of’54. The original two-tone covering exhibits limited wear (particularly when considering the fragility of this material compared to a conventional tolex or tweed), primarily concentrated around the edges, and half of the gold Gibson badge is still intact on the amp’s face. The graphics on the brown faceplate are clean, the brown chickenhead knobs are present, and the leather handle has been replaced.

Up for sale, a 1964 Gibson Falcon GA-19RVT combo tube amplifier in excellent condition and in perfect working order. The early Crestline-era Falcons are great sleepers, as they feature nearly identical circuitry to the more sought-after Tweed-era Gibson amps. Cleans are clear and bouncy, and the Falcon is the perfect amplifier for small club gigs and studio sessions with a smooth, harmonic rich overdrive when opened up. The Reverb is quite lush, and the Tremolo has a nice pulse with a good range of speeds. A single channel design, controls consist of Loudness (Volume), Tone, Reverberation, and Depth and Frequency knobs for the Tremolo. The original footswitch is included, and features a separate on/off switch for both the Reverb and Tremolo effects. The circuit retains its original transformers which all date to 1964, and the circuit is extremely original with just a few capacitor substitutions to ensure optimal functionality. The power cable has been upgraded to the modern three-prong variety. The tube set includes the original matching RCAs in the preamp, the stock RCA rectifier and a modern matched pair of JJ-branded 6V6 power tubes. The stock Jensen C12R 12 speaker is intact, dating to the 32nd week of’64. Cosmetically, this amp is in great shape with the original dark gray textured covering and two-tone grillcloth, showing only light wear on the enclosure edges. The original Gibson badge and luggage-style handle are also intact. The aluminum faceplate shows light surface patina with clean graphics and original reflector cap knobs.

Works great, sounds better!

Up for sale, a 1953 Gibson BR-6 vintage tube amp in excellent condition and in perfect working order. Freshly serviced by our techs here at Mike & Mike’s Guitar Bar, this BR-6 is the three-input version as redesigned by Gibson in 1948, and one of the first examples to shift the chassis from mounting to the bottom of the cabinet to the top. Loaded with a vintage (replacement) CTS alnico magnet 10 speaker, the tone is warm and fairly dark in its voicing from 1-5 on the single Volume dial, gaining grit and overdriven roar pushing towards 10. The amp really shines when dimed out with the midrange character unique to octal preamp amps and a real gutsy, punchy sound that’s thick and saturated. The point-to-point circuit features the stock IRC pot and power transformer manufactured by Magnetic Components Co, with a date code from the 25th week of’53, while the original output transformer is mounted to the speaker frame. New premium capacitors are manufactured by Sprague, while much of the original circuitry, including two of the famed Grey Tiger capacitors, is present. The vintage replacement speaker was manufactured by CTS, with a date stamp on the magnet from the 30th week of’70. The amp retains its original smooth brown covering, made from the same material used on early’50s Gibson guitar cases. The enclosure shows relatively restrained wear considering its vintage, and the wicker grillcloth is very well-kept. The large “G” gold badge is intact central to the grill, with the small silkscreened Gibson logo in the upper right corner of the amp’s face. The control plate has clean silkscreened graphics, and the one brown chicken head knob is intact. The leather handle is a modern replacement.

Gibson 10 speakers made by CTS or Oxford by the looks of them. The date is approx 1965 to 66 by the look of these. The Gibson orange label covered up the date & mfg code on the alnico magnet. I did not want to remove the Gibson. These speakers have been professionally re-coned by Slice Speaker Repair here in KC and sound incredibly good. The new surround and cones sound allot better than to vintage ones in my i opinion. Not different, just better. These can out of a highertrated Gibson combo so they are the high capacity ones that can handle the full power of a combo amp and dcr is 5.98 so 8 ohms. They are a matched set from the factory pulled from a working amp. On vintage replacement speakers.

Up for sale, a 1941 Gibson EH-125 1×12 combo amp in excellent condition and in perfect working order. Introduced in’41, just prior to US involvement in WWII, and only produced for a few years, this rare, early Gibson amplifier is the little sibling of the EH-150, pushing 10-12 watts of power via a pair of vintage RCA 6V6 tubes through the original field coil speaker. This amp features three inputs: one Microphone and two Instruments, along with a single Volume control which dictates only the Microphone channel (the Instrument channels are fixed/maxed volume). Tonally, this amp is sweet and smooth, with fantastic clarity and a kind of burnished warmth that one can really only find with the amplifiers produced in the very first days of electric guitar amplification. The Microphone channel, as the only channel with a Volume control, enables the amp to be pushed up into perfectly creamy edge-of-breakup territory, with a bluesy bite and just enough sizzle. The point-to-point circuit features the original pair of transformers (output transformer mounted to the field coil speaker frame), with a few new tubular signal caps installed as needed, and a modern Alpha-branded Volume pot. A couple stock signal caps and many original carbon comp resistors are present, and the power supply has been recapped with high quality F&Ts. A three-prong power cable has also been installed. The tubes are a matched set of vintage RCAs, including the 6V6 power tubes, a 5Y3 rectifier, and a 6SJ7 and 6J5 valves in the preamp. The original field coil speaker is present; the coil has been rewound and the speaker has been reconed. The original coil cover is intact, and there is a 1941 date stamp on the edge of the frame. The enclosure retains its original “rich Cordoba brown” covering, accented by a small Gibson silkscreened logo, with relatively restrained wear considering its vintage. The black metal grill is clean, the latches that hold on the removable back panel are all intact and functional, the original leather handle and leather corners are present, and the original chickenhead knob is intact.

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.

Up for sale, a 1957 Gibson GA-20 in excellent condition and in perfect working order. Featuring original two-tone cosmetics, a positively gleaming chrome faceplate, a Jensen P12R speaker, and a very original and professionally serviced circuit, this GA-20 is the perfect mid-size combo from the golden age of tube amplification. In many ways analogous to Fender’s narrow panel tweed amps of the same era, the GA-20 features a four input design with a 6V6 power tube pair, 5Y3 rectifier, and dual triode (12AX7, etc) tubes in the preamp. Offering distinctly different voicings between the single Microphone input and the three Instrument inputs, the GA-20 is at its most aggressive via the Mic channel.

The Tone control has an absolutely massive sweep, actually adding a bit more gain when turned up. Maxing out both Volume and Tone knobs yields a ripping, cutting sound that interacts equally well with single coils and humbuckers. The Instrument inputs have more range in the clean signal, with a full-bodied and sweet sound that works well with a host of effects pedals. Turning down the Tone knob on this channel and pushing the Volume can achieve a very nice bark and a spitty quality almost akin to certain fuzz boxes, depending on the guitar being used, and once again diming everything out delivers plenty of richness and roar. The point-to-point circuit has been professionally serviced, and the preamp retains a trio of original yellow Astrons, the same capacitors used in Fender’s narrow panel tweed circuits, and a key component in the musical nature of those preamps. There are a few modern Jupiter tubular caps in the preamp (which faithfully replicate the design and tonal properties of an Astron), and the power supply has been recapped with high quality F&Ts. The original output transformer is intact, and while it would have originally been mounted to the speaker frame, the transformer has been relocated to the chassis. The source-date code on the output transformer dates to the 14th week of 1957. The power transformer is a modern premium replacement courtesy of Mercury Magnetics, fitted with the original “GA-20″-embossed bell cover. The speaker is the original Jensen P12R alnico magnet driver which has a dark blue/green frame. The speaker has been recently professionally reconed, and the date code on the edge of the frame is from the 22nd week of’57. The original two-tone brown and fawn covering is remarkably clean, especially considering the fragility of this material compared to a conventional tolex or even tweed. The chrome plating on the faceplate is extremely nice, and the amp retains all of its original black silkscreen graphics. The gold Gibson badge is no longer present on the amp’s face, and the luggage-style handle is present.
