I went out combo shopping 2 months ago for a 300+ watt combo. I went to Guitar Center and checked out their stuff. I rejected the working man's, the Bassman 400, and a similar ampeg. It came down to the GK (540 watt 2x10+horn whose exact designation escapes me), and the SWR Silverado Special (a 350 watt 2x12+horn). I choose the SWR because it had a much warmer sound that didn't color my tone as much. I am gonna keep it, but I was looking for info/affirmation/berating/acvice for getting the most out of it from anyone who has experience with it. My experience is that it sounds great, really puts out alot of noise and looks like a million bucks with it's chrome grill and instrument pannel, and blue LED. The only drawback is that it is 93 pounds and a little tough to transport at times.
