FLO was originally a fernandes sustainer. that would have a dummy neck single coil for asthetics.
I know Vai sent an axe to sustainiac.com, but have no idea what happened there, or what he's using now. Not sure if his Ibanez contract would limit him from publically endorsing a sustainer, or posting more details. The lack of info presented leads me to believe that could be a factor, along with possible less than 100% satisfaction with whatever system is currently being used.
I can say after his NYC appearance for the NARAS that he should leave the sustainer axes home unless his guitar tech is not at his side to change batteries and keep it purring ...glen
if butch says it's a fastrack, then that's what is(was) installed. what is not clear is the wiring diagrams, what base sustainer system is installed w/ the fastrack, what additional mods were made nor what other sustainer axes are being used also... glen
i just talked to pete at fenandez he says in fact he did the work on steve's guitar and he uses the evo bridge pickup in conjuction with the sustainer and has a fasttrack under the cover in the pics which is just his pickup he uses in the neck of the guitar.
however does anyone know anything about the wiring of steve's guitars?
