Did you check out the link provided? https://guitar.com/features/gallery/the-story-of-brian-mays-deacy-amp/Actually May’s primary amp has always been a Vox AC30, which is indeed a tube amplifier. The amp you’re referring to is the “Deacy” transistor-based amplifier designed by Queen’s bassist, John Deacon, who had formidable skills as a technical engineer himself—and May used it primarily to simulate odd sounds reminiscent of string instruments on songs such as “Lazy on a Sunday Afternoon”.
But it was not responsible for May’s “tone”, which was largely created by the unique constellation of both in-phase and out-of-phase Burns Tri-Sonic single coil pickups, wired in series, coated with epoxide adhesive to cool off the sharpness of the single coil wiring. The somewhat nasal sound is a result of the neck and middle pickups being out of phase—his Red Special was tricked out with an array of switches allowing him to attain a vast array of tones. His sharp attack was aided by his use of a sixpence coin instead of a typical plectrum.
All this was augmented by his use of his choice of British tube amplifiers. If you think the soaring roar he created on his iconic solo in “We Will Rock You” was the result of a tiny transistor amp powered by a 9 volt battery, you’re kidding yourself—that was all Vox AC30 with Tung-Sol EL84s.
I have actually built several Fender Tweed ‘57 Champ amplifiers myself, with a variety of tube configurations. Clapton did indeed use this amp to record the main riff in “Layla”, turned up to full volume and enclosed in a wooden enclosure with close mic placement—and the stock tubes were indeed Tung Sol 6V6s. Walsh has used any number of amps during his career and rarely were they solid state.
What you meant by your closing “generalizations are rarely accurate” statement remains a mystery to me, but if it was in the service of sanctimony and officiousness, I’m afraid that your satisfaction is in no way a result of me feeling intimidated. Cheers!
Other searches produce results supporting the AC30 amp. Perhaps both depending on studio recordings or not. By generalizations - I meant convincing guitarists to not believe in their tube amps may be a moot point. I suspect the equipment used will simply be what is needed for the task at hand - tube or solid state.
