You may try Mike Fenton. Most of your star's picks have been coming from him. But they are all pretty much made from stock stuff, so you could ask... He used to work out of a place called Music Music in San Diego, CA. He even did alot of
Steve Vai's picks in the early days. I know he's still making picks...my friend Jan had some made. I'll see if I can get you some contact info for him.
