Re: Four amps at once

  Chris, thanks for the in-depth post.  According to what I'd heard, the
reason he  supposedly used the three banks of four was so he could apply
separate effects as you mentioned to each amp, in a single bank, and then
switch to a second or third bank if he needed to, as he'd apparently felt
that the AC-30s weren't very reliable.  <smile>  -so the set-up was a
redundant back-up just in case.  <smile>  who knows though, I'm sure
there's so much mis-info going around about famous players it's not even
funny!   lol!    I think people should just get a sound they like, and
become famous themselves!...    lol!  -Have a great day!...
