I recently bought a DV Mark 'Little Jazz' amp - 8" speaker, 50 watts. What does a 'jazz amp' imply to you? Clean, certainly, and warm and mellow. It does those things perfectly and is small and light. Great for a home practice amp (or jazz gigs) - and is completely free of hum or noise. But using my Squier CV Tele, it can have a clean country twang as well. And plugging through a Bad Monkey pedal, I can get that Danny Gatton/Roy Buchanan dirty Tele tone. Not yet tried it on a country gig, but it can be hooked up to other speakers... When I worked in studios in the 70's, session players for pop/MOR sessions would all bring in small amps - this would've been perfect.
