As a little side project, I plan on getting an Essex sunburst J copy and doing some mods to make it more like a personalized bass. Since Essexes are darn cheap and great for the money, what better bass to work on, right? One of the things I'm planning on doing is etching some designs or drawings onto the headstock, then staining the etches to bring out the linework. I would like to try it on the back of the neck too, but I'm afraid the linework would feel weird against my thumb and affect my playing. Has anyone done this to their headstock or any part of their bass before? If so, I'd like to see some images of how your etchings turned out, if they affected playing/tone in any way, etc. Also how easy/hard it was to do.
