I finally broke down and got me a Bag End Q10BX-D cab, and it should be here any day now. I don't currently own a head unit so I'm open to a lot of things right now, but I have a few heads in mind, and I'm hoping to get as much feedback as possible. I'm considering the following: Mesa Bass 400+ Ashdown MAG 600R Orange AD200B (Not too sure about this one; real expensive and I'm not a fan of distortion a lot of the time, but I've heard a lot of good about it) Possibly something by GK (RB series) Also thinking about preamp / poweramp setups, for example: Ashdown RPM-1 EVO II Preamplifier + Ashdown ABM APM 1000 EVO II Power Amplifier I don't know a lot about these kinds of setups though. Some more details about the cab: http://www.bagend.com/bagend/q10bx-d.htm Things to consider: 800w continuous / 1600w program 8 ohm impedance Later on I want to add one or more Bag End 15 or 18 or even 21 inch subs with their INFRA processor or possibly another identical cab like the one I just bought so I'd need a head to accomodate. The subs are also 8 ohm impedance. I've tried Ampeg and I really didn't like it. I think the cabinet I got had replacement speakers but even then it sounded terrible. It didn't project like I thought it ought to. I found the head unit (SVT4-Pro) to be complex and most of the options to be largely nonfunctional. So there you have it. I'd really really appreciate any help any of you can give me. Thanks a lot!
