I can't even remember how the bridge on my Hag 8 String worked , but I do remember the guy who made the bridge for my Earthwood borrowed my Hag for a couple of weeks so he could copy some of Hagstroms ideas and incorporate them for his own designs. He was a first class luthier with several patents for various acoustic and electric innovations. He was very impressed with a lot of things that Hagstrom was doing.In particularl, their bridge and neck designs.
