Bugera V55 Infinium 1x12" 55-watt Tube Combo Amp for sale. This is a very good and respected "clean" style tube amp, but also can do dirty! :). It includes the dust cover as well that I got for it separately. The price is "firm" as I paid noticeably more than what I am asking when I got it, and it is in perfect condition. These amps now go for around $720, I think.
