Hey, im in the final stages of building my rig, right now all i have is the avatar 2x10 from my old rig. i want to buy the sansamp RBI and a QSC hopefully PLX power amp. Do many people on this site use this set up? or played it? how do you think it will sound for a rock n roll band. im looking at adding another cab later on, 2x12 or 1x15. any ideas? also i want to keep my rack small, 4 or so spaces. what do you recomend? RBI 1 space QSC 2 spaces 1 space extra... should i leave it blank to let it cool down a little? Power conditioner? Let it be for now and add something later, when i know what i want. thanks!
