I found a three part video interview with Joe Bonamassa over on the Guitar Noize blog.
Joe talks about his rig in great detail in the video series as well as his guitars. Joe calls his four amp setup the “monster rig” but the way he has it set up ends up being a very simple concept.
Another key component to his rig are the EV12L speakers. These speakers weigh about 20lbs each and sound like it too.!
