I bought this head from Sweetwater about a month ago. I started playing bass in 1979. Over the years I have owned just about every brand you can think of "including Mesa". This thing is by far the most musical head I've ever had the privilege of playing through. It's fat, clear, and defined. I really like the weight "or should I say the lack of weight" for a tube head. I have pushed a couple of different cabs with this little monster, and have failed to get a bad tone. I know everyone always says "this will be the last piece of equipment that I will ever buy"... but, I truly believe that's the case with this thing. Don't worry about the power rating. This thing has headroom for days. I can not praise this this head enough. I know it's a little pricey, But knowing what I know now.... I would pay even more for it. A lot more!
