I think I remember seeing the article with Steve Vai's workout in an old issue of "Guitar -- for the Practicing Musician." I don't believe that the magazine is still being printed, but I think that the people at "Guitar One" used to be affiliated with the old "Guitar" magazine. You might try contacting "Guitar One" to see if they could help you. If you can figure out the magazine and issue date, then you should try going on one of the online auction sites and run a search for the name of the magazine. I know at one time ebay had a lot of the old Guitar magazines for sale and I was able to get a back issue that I was looking for. Also, if any of those rock & roll memorabilia conventions periodically come to your town, they always have tons of those old guitar magazines.
:cool:
