Right now i'm running a qsc rmx 1450 and an rbi sansamp through an ampeg 810e. Frankly i'm sick of lugging it around, my rack is rattling apart, and the cab is getting destroyed . I want to downsize but still keep up close to my current sound. tone is not as important to me as power. I can tweek the tone as long as i have the power. I always run direct anyway to i just need to hear myself on stage. i realize that nothing is going to recreate what i currently run but the fact is, I hardly ever have to throttle my amp. I do occasionally but i'm pretty sure i could get along without all of that power. I'm looking at a couple of different amps. i'm eye-balling the trace elliot,markbass, and the ashdown. They are all 500 watt solid state with a 15". What do you think? Am i going to be comepletely disapointed if i downsize to one of these?
