I have a question about the stop tail piece on Les Paul style guitars. I have noticed that some LP players wrap the strings around the top of the bar ie. Joe Bananamassa, and Zakk Wylde; versus the traditional way of through the rear and out the front and over the bridge. Why is this done, and what advantages are there to routing the strings through the stop tail piece this way? http://www.helidriver.com/guitars/GuitarPics2.20.09/R8TopWrap2.jpg versus traditional style.
