Saw both bands last night. ZZ Top made Skynryd sound like a garage band. I had pretty good seats, right by the sound board. Skynryd was an echoey mess (as most every band is in an arena) But ZZ top was so clean you could eat off it. Album clean, perfect tone. Even his string noise sounded perfect. Anyone know how these guys set up and maintain that kind of sound in huge rooms? I'd love to see photos of his rig & Isolation room.
