Got the new Euphonic Audio Iamp 500 today. This thing is sweeeet! So far I've only done some bedroom noodling but this thing gets really loud and is tonally very flexible. I've never been a big fan of contour switches but I see why people rave about the ones on this preamp- very usable and musical. Its just slightly larger than I was expecting at 14.5"x9"x3.5" and weighs in at about 13lbs. I think I have finally achieved my goal of having a moderately loud rig that I can move up a flight of stairs in one trip. I have a few gigs this week and next and will post more as I use it if anyone is interested. Oh one thing - I can't seem to drive the input section into clipping with my passive jazz style bass. Is this common with EA's amps and should I be concerned about not getting full power from the amp?
