It's not what you think. Hamer Guitars had one back in the day. I remember the Andy Summers model had this in it. I was lucky enough to play one when they first came out. Now Mighty Mite makes one but it's the regular humbucker configuration. I wish that someone had this again or that I could figure out how to reproduce it now that Hamer exists in name only.
