So I've come to the decision that I really don't need to waste rack space with a bulky tuner and power conditioner. I can use light, small, non-rack alternatives to both. My question: With a Mesa-Boogie M-2000, is it possible for there to be any benefits in using the SansAmp RBI? It is stated to "optimize your amp's output relative to the P.A. system". Considering that I have been dissatisfied with the direct out on my M-2000 (after recording and hooking it into a PA board), I am wondering if this can be used to further optimize my tone and assist in optimizing my amps output (ect.). If so, how would this be done? Would I put the RBI into my heads effects loop and use the RBI as the DI to the PA? <-------(would that eliminate the M-2000 preamp(s)?) Hmm.
