Re: Would this work?
Eddie used a speaker sim in the 90's, set up the same way as the dummy load with the Marshall. Outboard power amps hit the 5150 cabs. Even though there's an effects loop in the amp, he didn't use it. Also, there's always one head in the live setup that feeds to Alex directly, no effects, just the dry signal.
But, since at least the first major tour in '78, he ran through a dummy load to put the effects after the amp.
I've got one of the guitar mags from the 90's that has his full rig setup in there during the For Unlawful Carnal Knowledge tour. The Balance tour was pretty much the same.
