Hey man. I used to own his entire setup, including amped svt-4 pro, pearce preamp, ampeg 8x10 and I own two of his basses ( red one and a blue one, both autographed by him in syracuse ny last year). I know how to get his sound. You don't need all that. You can get it with a p bass with dimarzio model p pickups or one of the limited attitude basses. I use a boss lmb-3 for compression and voodoo labs sparkle overdrive pedal for distortion ( you can mix your clean sound with the overdriven sound) The mxr m-80 also works well but I prefer to use the sparkle overdrive. This will give you his gritty tone which he uses most of the time. For his crazy full on distorted sound, a boss metal zone will come close. Beware, the metal zone will suck the low end out of your sound, even when disengaged! Put it in an effects loop , I use the boss effects loop pedal for this. I used to own the billy sheehan preamp and found the these pedals to do just as good of a job and they are more versatile. One last thing, use plenty of upper mids in your sound. Good luck. This advice will save you the tons of money i have spend to arrive at his sound. Chris
