A big IF I decide to do this, but if I get chicken heads for my Thinline... They're gonna be set-screw. so is there a preferred way to position them, or is it strictly a personal thing? Like staring at the guitar front (not holding it) where would the pointers point at (12 o clock., etc.) with the knobs zeroed out? I'm thinking that at mid-level (5), they would be at 12, but I have no idea.
