Any progress on your project? Following it closely hehe. I received the Hipshot bridge, but found out that one needs ball-ends as well, so if I wanted to keep the original black NK headpiece, I'd end up having to use double ball-end strings. But the problem is that these won't fit through that original headpiece. So I'll either need to go the the accompanying Hipshot headpiece (but not sure whether the head is long enough to accomodate that one at the right string angles etc), or perhaps ask my luthier to look at your solution Thanks for pioneering man!
