I would definitely not mess with a toploader.
Thanks, y'all. As I mentioned it was a theoretical question. My only objection ever to my beloved L2K's is my built-in dislike for pickup selector switches; I like balance pots or 2 volumes ...my problem, I know. How about a way to rig up 2 volume pots, a la jazz bass? Again, theoretical, but is it possible w/out physical modding of plate or body? Don't worry, as I said, I no longer have one around the house to tempt myself
