Hi! This is my first post in this forum, so please bear with me. On to the question: Do any of you know of some company that manufactures an aluminium seven string tune-o-matic stop tailpiece? I've been looking everywhere for days but seemingly no one makes one, only the usual zinc ones. Also, is there somebody out there doing seven string tune-o-matic bridges from steel? Maybe Callaham? Any experience on the subject?
