Well...i am a guitarist, and i am looking at a new amp. Currently i have a Marshall Valvestate 80w. It's pretty awesome, but i need something...more metal. I've been looking and researching for a long ass time. I've basically narrowed it down to the Peavey 5150/6505 series. I know there's diff. ones so what ones the best? Also i had a quesiton about rack systems, i'm not totally up to date on what they are, would they be better/cheaper? I know a little bit about it and i've been looking at the Lee Jackson GP-1000 Preamp, Peavey Classic 50/50 Power Amp, and i'm not to sure about a cab yet. Could anyone tell me good products for a first-time rack? Also what are all of the components to a rack, do i have it down? Thanks for looking!
