Well, since I have too many basses, and not NEARLY enough ways to amplify them, I went ahead and traded one of my Brubakers for an Aguilar DB659 pre and some cash. The cash I got was enough to purchase a QSC PLX2402. I should be getting all that stuff next week and will post a report here. My current amp is the Ashdown ABM900, which sounds great--no real need to change, except that my Ag DB900 tube DI sounds great (just ask StErLiNgBaSsIsT!), so I figure the Aguilar sound might do me some good.
