This little tubeamp is very versatile. A real good piece of German technology. If you switch it on it looks like our christmas tree but with a so much better sound :-)) I especially like the clean tone which is a trademark-sound from H&K amps I think. The rocktone is also very good, it can scream at loud levels.. Has a build in power soak 0/1/5/18/36 Watt and a build in redbox (speakersim). Its really small and handy carrying around to gigs or if you don't like it light enough to throw it out of the window... I play this and my Marshall Plexi. Nothing's missing in my dreams for now...if you're talking about tube-amps.
