Ok, Just hurt myself pretty bad hauling my gear last night, need to downsize. I had a 160 pound Basson 410, and I downsized to a 70 lb Schroeder (oooh so much better), and now for the head: Right now I have a Korg tuner, a BBE BMax T preamp, and a Crest LT 1000 power amp, all in a road ready case. I love the sound of this setup, and the Crest gives me 1300 watts at 4 ohms (cabinet rating) so I never even come close to clipping. However, it's all just too heavy. I LOVED the AG500. I could scrap all of the above for the AG500 in a two space rack bag, but I'm VERY concerned it wont have enough power to get the Schroeder pumped enough to slice thru my guitarists' 5150 full stacks. I REEEAAALLLy need to be VEEEERRY loud, and with the current setup, I have plenty of breathing room, but at the moment, I'm popping Advil like candy for the pain in my back. Who has any REAL WORLD experience with this head thru bigger / higher load cabinets?
