I've been giving the ol' Martin more and more home time and gigging with a Hohner acoustic. It plays just fine but seeing as it's a cheapie (less than $400 with elctric pickup) I was thinkin' of getting some of my musican friends to affix their autographs to it.
What kind of pen works best? It has to be a perminent ink that won't bleed once the autograph dries. And since I'm going to continue gigging with it, I would like an ink that is somewhat durable.
Other than "Don't do it" any suggestions as to what kind of pen is usually used for doing this?
