I'm looking for a very cheap deal on dual 4x10's and a head. But I need to know how cheap is too cheap. I also need to be advised on what I should look for in new and used cabinets. I barely even know where to start on all of this, so if you have any other advice that you think would be relevant, please include it. By the way, I use a DigiTech BP-200 Multi Fx Pedal and a Schecter Diamond Series 4 with active-soapbar pickups.
