"I have four DB 750's with a compressor and it's blaaaaaazing hott! Don't get scared - I don't use all of them simultaneously! I also have six GS 410's that I'm using. I used to use four cabs for my bass and two cabs for my keys but I was killing the front of house engineer. Now I just use two for bass, two for keys, and the other two are my backup. I have never used any rig with so much booty. My sound is huge even with just two GS 410's."
