Just some random wanking. Please excuse the sloppy playing.
Evo Clip
Signal:
Ibanez Jem with DiMarzio Evolution pickups > Boss Keeley Ultra DS-1 Distortion > Ibanez AD-9 Analog Delay > Mesa Lonestar Head, Clean Channel > Mesa Standard Rectifier 4x12 Cabinet > Audix i5 (off axis) and Studio Projects C-1 (on axis) and I added some Waves plate reverb in post.
Snapple is right, though. Only Vai and Satch can sound like themselves, but their tones aren't too impossible to conjur up if you know their rigs well enough, which aren't too complex.
Steve uses Jems with Evolutions and Breeds into a Bad Horsie Wah, a Keeley DS-1 (or a rare Japanese DS-1 from the 80s) into his signature Carvin Legacy amp. he also uses a Digitech Whammy, though I'm not sure if it's before the amp or in the effects loop. The effects he uses are quite pricey, though, especially the Evantide stuff. He controls everything from his Bradley switching system his tech set up, which is ridiculously expensive.
Satch, on the other hand, has a much simpler setup. His signature JS guitars into the same DS-1 (Keeley or old Japanese) into his JSX amps. And I think he only uses a few pedals in the effects loops. Pretty simple. Alot of the time, Satch doesn't even use the distortion in his amp. He'll just his DS-1 into a clean amp, which is what I did for this clip. Have fun with your new guitar.
