i don't know anyhting about amps. i have 1200 to spend. i'm thinking i really want a GK 800RB head and a GK 1x15 RBH cab. how does the SBX compare to the RBH? the RBH is 400 watts and the SBX is 200. i play medium sized bars. do i need 400watts? i play funk and groove music so i'm looking to shake butts not cut through and split ears. i've heard that the RBHs are pricey compared to what you get. does ampeg make any 1x15s that are more cost effective to the quality. i'll spend 600 on the cab if it is really worth 600. also i've been reading this amp board a lot to learn more. i'm thinking i'm going to be really confused when i get it after hearing all this amp lingo. i hope i don't blow the thing up. i sold my old combo. i have practice in a week. PLEASE HELP.
