Very cool of you to offer.

Sorry if my terminology is wrong - I'm pretty new to the guitar. I thought it was called a "bridge nut" after looking at this picture - http://www.mangore.com/guitar_parts.jpg

So it's that piece the strings first touch after they come out of the face of the guitar. Some buddy of mine called it a saddle - I've got no idea what the real name is.

Thanks,
