Marshall: Awesome. I love the tone of these amps. Wonderful quality of sound.

Vox: Haven't heard much from them...

Fender: Similar to the Marshall, I don't like it as much though.

Matchless: not as much as it would like to think.

Mesa-boogie dual rect: Bah

Crate: Wonderful amps. I really like the larger half stacks and full stacks that come out of this company.

Peavy: I own a really really awful Peavey, So I'd like to say all their amps suck. But that's really not the case. I think Peavey makes some pretty good amps, but I really like the fender and Marshall amps better.
