I'm looking for something that would be an upgrade from the svt 3 and a sonic 610 that I have now. Both are rated right around 550 watts so they work well together. However, I just don't feel that this rig is providing adequate rockage. I'm looking to upgrade and brainstorming possibilities. I know that I want a head that's at least 600 watts, unless it's tubed, then 2 or 300 would be fine. The cab is around 115 or so pounds which is okay but I don't want to get much heavier than that on a single cabinet. I'm thinking about getting an eden wt-800, I used one of those in the studio and thought it sounded great. If I were to get that, would buying an aggie gs412 make any sense? I don't know how the rig would sound but I've convinced myself that I really like those cabs, they're lighter than an 810 which is good, and I've heard real good things about the sound and volume they can make. I know I like the Eden head. Would the two work together, and if not are there any other recommendations for possible combinations?
