I LOVE John Mayer's tone. Seems he's using his Signature Two-Rock amp - which is a Custom Reverb Sig amp with some mods. I've seen him also with a Bassman (Victoria, not Fender, I think).
What are these Two-Rock amps based on?
Completely new design?
Or something based on the Fender eras? Blackface, Brownface?
These amps seem to have the headroom of a Blackface, but not as bright or as "cold". They seem more hot (though punchy), like a Tweed.
Now, I'm a noob about tubes and amps, so please correct me if I said sth wrong.

What about the Carvin Belair?
