It looks like he's using the Vai legacy drive pedal as a preamp into power amps now, no idea why he'd stop carrying the legacy's around with him, probably cheaper shipping it around this way or something.
Wait what amp is he using here? It sounds like his tone from the g3 with malmsteen. It doesn’t seem super new but it does seem slightly modified. That might just be the guitar though. It does sound like his bad horse guitar from the dvd of him live in what I think was England?
