The Deluxe Reverb (blackface, of course ;-), my favorite amp. Dwight Twilley’s long-time guitarist Bill Pitcock IV (now RIP) used a pair of them with an MXR digital delay between the two, with an ES335 plugged in. Awesome live sound!
When I recorded with Evan Johns in Atlanta, his Deluxe was up in British Vancouver, so he plugged his Tele into the studio’s black face Super Reverb, and cranked it to 10. Loudest thing I’ve ever heard! One Fender I really dislike is the Twin Reverb---too metallic/brash for my taste, though Mike Bloomfield made his sound pretty damned good (with a Les Paul).
The best live guitar sound I’ve heard was that of Ry Cooder. He had a pile of a half-dozen old combo amps: Fender, Gretsch, Ampeg, etc. And his playing? The best I’ve ever heard. This is related to the topic of the post because when Ry played his little solo in John Hiatt's "Lipstick Sunset", it felt like time stopped. The single greatest musical experience of my life.
