I adore mine, I was shocked the first time I heard the vintage high channel roaring through. It got rid of my interests in Shivas or Rockerverbs.
It's a Mesa, so of course the 1x12 is ridiculously heavy, but it's built to withstand a car crash it seems. I wish my gear didn't have to live downstairs, and then require me to drag this up every time I've got a gig, but of my 3 amps this is my main cover band amp now.
The only thing I wish it had was a footswitchable solo boost, but I have an MXR 10-Band EQ I don't use for anything, so that's my clean boost now, which works perfectly.
I also like the 45-watt mode, by the way, it lets me get a fuller sound at home practice volume without having to plug in my THD HotPlate.
