Vox AC15cc

I don't like them (this is after over a year of playing/hearing one every day at work). I'd rather have a Fender Hot Rod Deluxe for cleans and bluesy dirt, hell I'd take a Crate Blackheart combo over an AC15.
 
I have a hard time imagining any company that could do cleans better than Fender, so if my JSX weren't so tits at 'em, that's what I would consider...
 
I don't know dick about models, but I'm sure a great used one could be found on ebay (after all, consider how one of the greatest metal amps that needs no mention is usually around $600 on ebay)
 
Fuck the hot rod series. I played a deluxe for around 1 year and it sucked.
I currently have a boner for a Bassman '10. It's a 4x10 combo. Very sweet.

Put a Jensen P12Q in a HR Dlx and you'll know what I'm talking about, stock they aren't great.

OP: Try the 57 Deluxe too, or "The 57" if you can find one. More expensive but amazing amps.
