Introduced in 1953, at the time it was the first amp in existence with such a lavish complement of speakers (six 8\" -Fender's 4X10\" Bassman having started the trend) and a major advance on previous Gibsons. This amp was intended for use with guitar, accordion, microphones and especially Gibson's new Electric Bass, which had a big dark sound and was notoriously hard on speaker cones! The tightly-engineered GA-90 offers the dark midrangey hi-fi sound Gibson favored, and has a slower breakup curve than most 50's amps. \u003cbr\u003e\u003cbr\u003eWhen pushed, this amp snarls in a particularly authentic 1950's sounding way but does not slide into the screaming overdrive characteristic of many Fender or Chicago-made models-that was considered an undesirable inconvenience at the time! There are two discreet channels, each with volume, bass and treble controls; the mic\/accordion channel offers a high\/low gain option. Output is around 25 Watts. The preamp section is mounted above the speakers, with the power amp on the bottom-another Gibson innovation. A cool find in a period Gibson and a uniquely voiced vintage amp, especially suited to period or modern musical styles where tonal clarity is a concern.\u003cbr\u003e \u003cbr\u003eHeight is 21 in. (53.3 cm.), 25 1\/4 in. (64.1 cm.) width, and 9 1\/2 in. (24.1 cm.) deep. A lovely and beautifully preserved amp; appears unaltered except for two recently replaced power tubes. Otherwise all original components including knobs, speakers, electronics and even the 2-prong cord. Covering has some small dings and a several small (1\/2\" or less) tears at the bottom corners and edges but not a lot of wear overall. A superb example! Overall Excellent Condition.","brand":"Gibson","offers":[{"title":"Default Title","offer_id":46853411471500,"sku":"5377","price":2200.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/8702\/3756\/files\/01_2ba3ff8c-52a8-499c-82ed-f6c1207dee35.jpg?v=1774338006","url":"https:\/\/retrofret.com\/products\/gibson-ga-90-high-fidelity-tube-amplifier-1956-5377","provider":"RetroFret","version":"1.0","type":"link"}
