Just wondering if the process started as using the AXEFX into the actual amp they are matchings FXRETURN to first dial in the preamp to match no cab sim on. Then go into a power amp like the Matrix or something to then tweak the power amp section through some sort of say 4x12 cab for most higher gain amps and just comparing them side by side. I'm sure this is the obvious procedure to really match them up. I was just wondering because I know all the amps were redone to match and would just buy the exact power amp Cliff used to dial them in. It may have been posted already but I must have missed it and could find in anywhere. I'll just buy the actual setup used in the final process that the man used to dial them in to know I'm maximizing my AXEFX.
