In some cases, uniform string angle at the bridge can improve guitar response. Rosette Diamond String Ties allow you to tie your strings in your hand. By attaching the string to the 3 hole bead, you eliminate the cumbersome task of tying strings to the bridge block. You simply thread the string through the back of the bridge and attach it to the roller. With minimal experience, you can reduce your string change time! Now free shipping world wide!
