Wes,
You're correct. Zlx-12p. I got to open it up yesterday. Sounds amazing. Like said the the dumble drive sounds great. That particular rig reinforces the fact that the 11rack does a great job. The tone is in there. You just have to put in the time.
I got the zlx12p, roadrunner case and a 3 yr extended warranty for $580 out the door. I'm going to jam tonight with buddies and I think it will do just fine.
Good luck Wes.
Just noticed you're in Indy. I'm just down in Bedford and work in Bloomington. Small world!:)
