In my quest to build a Bass VI, I came across a cool site that lets you design your own headstock decals. I was planning on making up a model name for my Bass VI project, as to avoid the legal issues with making up a Fender one. Check out www.best-decals.com Go to the "Make your own Decal" section.
I see they're back. They were down for a while, I assumed they got sued. I have used 2 of their products. I have their John-Mayer style racing stripe on one of my strats, and on my tele, I have their (oversized, almost completely accurate) fender logo on the headstock.
