Cool!!! sounds awesome as I expected it would.
I tend to leave it in "OLD" all the time now unless we're doing some of the 70's stuff I don't play lead on.
on my head it just makes it sound thicker and ballsier.
We do some Bad Company, Atlanta Rhythm Section , Frampton and Foreigner stuff that I don't play lead on and I switch it back to new
for that stuff, sounds a little more open and more "polite" in "New"
