I've got an Aguilar DB750 in excellent condition. It's been kept in a heavy-duty rack, so there may be a little scratching on the top/bottom, but that's it. This is a totally slamming head that has been my main rig with my rock band for a couple of years, but I'm getting tired of hauling around a big rack setup and thinking about a partial trade for a lighter Class D head. I'm particularly interested in the Darkglass Microtubes 900, since distortion/overdrive has become a much bigger part of my sound these days, but I'd be interested in other lightweight heads as well...
