hi,
sir Vai in alien love secret uses Bogner,old marshall (arredondo plexi and jcm 800 i think)and go at 4x12 with room mics(3 i think)2 at the corners of the room and 1 at 3' out of the cab.So he goes out from the d.i of the amp and go in a sansamp (maybe a psa1 but i suppose the old sansamp but i am not sure at all)into a speaker simulator and he mix this 4 or 5 lines to obtain a good sound that he didn't double (he added ,maybe, a 30ms or so of digital delay that make the track more fat).This is for me the sound.In the dvd alien love secret he explain it in the track juice but i don't know sir Vai is sir vai.I think he uses a d.i. (maybe avalon in clean sound) direct in the console and a bogner i am sure an ecstasy for distorted sound.The settings for me are the same like vai
