Hi,    The main purpose of that bridge is to adjust intonation, as I understand it.  Speak with Joe Collins, who is affiliated with NHD.  He is very helpful.  Good Luck!  

Anybody out there know anything about the New Harmony instruments bridge? The main question I have is about the Accutune module bridge. Any idea can you adjust the action and then lock everything into place so it doesn't get out of adjustment? Or you just adjust it for intonation, and no option for action, and it has a tendency to move out of place?
