"I use a variety [of amps], like on the record I used a lot of different guitars, but usually they were textural stuff for the background. For the most part, I used the Jems and the Evo and Flo for the leads. It's the same thing with the amps. It's just a comfort level thing... These guitars and equipment are custom built specifically for my ears and fingers, so it's like a comfort zone - it's like home. The first one, I've had a longstanding relationship with Carvin since the early 80s. I think it was maybe in the 90s when we started talking about making a custom amp. Now I wanted something very simple because although my music is very complex at times I really like simplicity when it comes to amps and gear because who wants to sit there and try to figure stuff out. So it's a very simple amp, there's two channels: there's a dirty channel with presence, treble, mid, bass, drive, and volume, and a clean channel that has similar. There's also effects, loops, and other conventional stuff in the back, and you can flip it to different wattages as well. Now, you want to continue to evolve and try to improve the Legacy 2 amp and I ended up not liking it as much as I like this one, the Legacy 1. But I was feeling limited because there were only two channels and there was no master volume. I like to be able to turn the level down without changing the tone, which is very rare because a lot of times the master volume is before the pre-amp on most amplifiers," says Steve Vai about his Carvin Legacy 1 VL100 100W Amp Heads.
