I did a show a few years ago with another guitar player who used a
JC77, while I was using an old, orange cube-60, and this guy buried me
with the sound he got out of that thing.
That was the last time I ever used my cube professionally. He also had
a rack unit that must have added a lot to the amp's output.
He was so loud that he drowned out the entire production, and the
director and conductor both begged him to turn down.
I subbed for him in a big production in NYC for him once, and listened
to him demolish an entire string section with his JC120.
I used his JC120 and played with proper dynamics, and they loved me
for it The JC120 is a great amp for my B120, but too heavy.
I think it sounds better than my SF Twin with my B-120
