Query: Excellent

I've had this amp for about a year now. It's a great investment. There are a couple problems with circuitry sometimes--about once every 3 months it goes whacko, but you just do the reset that they tell you how in the instructions and it's good as new. You can get pretty much any sound you want, though getting just the right distortion is a lot of work. The 4 button footswitch is $75 here so be prepared to pay if you want it. I dunno, I find like the blues sounds and the clean/classic crunch just a little weak and underresearched, but pretty much everything on this amp is excellent.
