Among the more interesting amplifier offerings to have come through our shop in some time, this 1957 Gibson Maestro GA-45 Accordion amplifier is rare, unusual and exciting.

The Gibson-made GA-45 is a dual 6V6 Class A amplifier that shares similar circuitry to Gibson’s GA-40 Les Paul guitar amp. One key difference between the two models is the 4×10″ speaker configuration of the GA-45 as opposed to the single 12″ in an era-equivalent GA-40. Additionally, the GA-45 offers a wider range of tonal sculpting in the form of separate Bass and Treble controls.

While billed as an accordion amplifier, the GA-45 packs serious punch when paired with a guitar. Offering a warm and full voice with excellent clarity and strong low-midrange presence, this amp will make any guitar sit beautifully in a mix. Delivering harmonically rich and wonderfully creamy breakup tones at reasonable volumes, the GA-45 is an excellent amplifier for any rock or country setting and excels in lead guitar applications. The Tremolo on this amp is clean and clear and is well controlled with an excellent range of depth and speed.

Back at our shop with a clean bill of health after some general servicing by Toronto’s Dom Tantalo, this 1957 Gibson Maestro GA-45 amp is in perfect working order and ready for any stage, studio, or collection.

This amp is largely original and in overall excellent condition. The transformers, speakers, and circuit are original. The RCA preamp tubes in V1 and V2 are from the ’70s, but all other tubes are original RCAs with ’57 date codes. Filter caps have been updated and the original power cable has been replaced with a grounded one of modern spec.

This 1957 Fender Harvard 5F10 amplifier offers responsive and full-bodied cleans at lower volumes, while boasting open, creamy, and harmonically rich breakup tones when pushed. It’s a remarkable sounding tweed amp that responds well to just about any pickup that you can imagine.
An excellent example of a “Narrow Panel” tweed amp, this late 1957 Fender Harvard 5F10 is largely original, apart from a few components replaced as part of general servicing. Both Triad transformers are original to the amplifier. The original Jensen speaker, dating the the 42nd week of ’57, is in great working order with a small patch repair making the original cone structurally stable. The original volume and tone pots date to the 38th week of ’57. The tube chart and chassis bear stamps of “GK,” indicating November 1957 production. The original tweed, grille cloth, handle, and hardware have aged beautifully over the last 68 years and remain in overall good condition.

Having been recently serviced by the GTA’s Dom Tantalo, this amp is studio and stage ready. Leaking filter caps have been replaced, with the new capacitors rehoused in the original cylinders in order to preserve the 1950s aesthetic of the circuit. The “death cap” has been replaced with a non-shorting class-Y cap. The original two-prong power cable has been upgraded with a modern grounded cable.

Introduced in late 1955, Fender’s Harvard filled the gap between the Princeton and Deluxe in the company’s line of amplifiers. Housed in a cabinet with the same dimensions as the big-box Princeton, the Harvard boasted an upgraded 10″ speaker, two 6V6 power tubes, and approximately 10 watts of power.

A reproduction of Marshall’s famous model 1962 “Bluesbreaker” combo – made famous by Eric Clapton and his recordings with John Mayall and the Bluesbreakers – this 1990 JTM Tremolo 50 features a 30 watt circuit, GZ34 rectifier, EL34 tubes, 5881 power tubes, and a pair of Celestion Greenback G12M 25 watt speakers. The amp is in excellent condition, appears completely original, and works perfectly.

There’s nothing that sounds like a Bluesbreaker. It is about as close as you can get to British overdrive heaven.

At about 65 lbs this amp isn’t going into a shipping box, sorry. Local sales only.

The Fender Pro Reverb was introduced in June of 1965, and has the distinction of being the only model of Black-Panel amplifiers that wasn’t offered in the pre-CBS era. You won’t find a ‘Fender Electric Instruments’ Pro Reverb.

This example is incredibly clean and is in perfect condition. It’s just been serviced by Dom Tantalo (Filter, bias, and cathode bypass caps replaced, a few non-original tubes replaced with NOS versions, clean, test, etc), and it received his high praises. Tube chart date of April 1967; transformers all date mid 1966 to the first week of ’67. Both 12” speakers are original but their date codes are obscured by stickers.

About 35 watts, 6L6 power section; incredible clean headroom with a little bit of sizzle when you get past about 4 on the volume knob. One of Fender’s best sounding models, and an incredibly versatile amp.

With original cover and foot switch.

No shipping, sorry.

The Marshall 1958X is a made-in-England hand-wired tube-powered combo amp that delivers about 18 watts through a pair of Celestion 10” speakers. It’s a reproduction of the company’s model 1958 combo that’s become exceptionally hard to find on the vintage market.

This Marshall 1958X is completely original, very clean, and in perfect working order. It sounds incredible, as you might expect, and will leave you wanting for nothing. It’s small enough to take along between gigs and sessions without much effort but still big enough to deliver what most of us around here think as the perfect amount of power.

With original footswitch.
