Yeah Vai does play FtLoG on Flo now, I saw the video of him in Holland with an orchestra, which was pretty amazing if you ask me
The guy at my local guitar store is a proper tech guy who deals guitars on the side. Basically, its a small guitar shop on the side of his operation theatre

Of course, I will ask him if he has ever installed one before because the chances are that he has installed quite a few fsks in his own guitars.
As for why I want it: I have been lacking
sustain which may be a result of my crappy marshall cab (which I am now replacing with a 5150 4x12) but Im confused because usually Laneys have awesome sustain. I saw
Steve Vai using a fs, obviously and I thought it was a brilliant idea. It would sort my sustain problems out and enable me to play anything I like (with the practice, of course

).
Thanks for the advice though
