First, allow me a quick introduction - I am a graduate student in history, a laid-off truckdriver, and, more to the point, a former professional soundman (as well as The World's Worst Guitar Player). I've been reading these boards for while just for sh*ts and giggles, and to learn from all you folks (but mostly because I love, even if I can't afford or play, great guitars and basses), and have almost registered several times just to chime in on these recurring amp discussions. Tonight I could hold my tongue no more, so, for what it's worth....in my soundman days I used Crown, Crest QSC, BGW, Peavy, Traynor, and probably a few others whose names have fallen victim to my misspent youth. Use what works for you, of course, but the only power amp I would spend my own money on is Yamaha. Not only do they have the best sound I've heard (that is, they have no sound - what you put in is exactly what comes out, uncolored and undistorted, just a LOT louder), but they are the ONLY brand that never let me down mid-gig. These things are freakin' bulletproof. Yeah, they're heavy, but hey, that what us roadies are for, right? Ok, sorry for the interruption, I'll be quiet now.......
