Live Bass Setup

I've been asked to play some live gigs for a few friends and clients, so I figured I should redo my bass rig. I'll be using an Ampeg SVT 410 HEN bottom with Altec 50 watt or 100 watt heads depending on the size of the venue. I'll be using a Line 6 PODxt for a preamp. It sounds fabulous. I tried old Bassman and Showman heads and just didn't like the sound. They lacked the versatility of sounds that the POD brings.
