I've been using a Ashdown MAG 2-10 Since I started playing bass and it's never let me down. They're built like tanks (All I've ever managed to do is crack the plastic corner covers a lil, and blow a fuse once) and put out sound that will rattle most venues (using everything from an acoustic bass to my Thunderbird). I've heard/seen a few bands use the ABM and they've all sounded fantastic, and should the opportunity ever arise for me to upgrade to that I would, just for the added umph from the tube.
