As a huge fan of the clean tones of The Smiths I wanted to create the same clean base sound. You get that instantly with the Twin Reverb. My vibrato channel breaks up/distorts quite often though. That's a shame because that's the other great thing about the Twin Reverb, the spring reverb and the vibrato. I will get it fixed in the near future. So, final verdict: great for clean play (check out Cobain and others to see the distortion possibilities), has a lot of volume and awesome reverb. May be a bit to much for the bedroom guitar hero, but not a show stopper.
I purchased this because it came with a Fender Rhodes.
It sounds awesome on that and on electric acoustic guitars.
This goes against what so many people seem to think, since it's one of the most coveted amps of all time... but I hate the way it sounds with electric guitars, especially clean. It has a sharp harsh tone with most Fender guitars. I'm not a fan of the way it looks as well, and would definitely opt for the '57 version over this model. Although they cost more, I'd say for electric guitar Mesa Boogie power amps with 4x12 cabs blow these out of the water. For a clean guitar tone at the same price point, I'd choose the Vox AC-30 or an Orange with tubes over this.
