Good to see how you exchange guitars from gig to gig. I do it the same way, I try to do justice to my guitars. One Strat gig, one Paul gig. I think supporting such beneficial events is a great thing. Although if there are no "musicians" in the audience you will be an important part. Good luck for the gig Robert.
