A rod secured across the width of the guitar peghead by a plurality of spaced apart fasteners, the rod having a roller disposed thereon for each guitar string, with each roller receiving a string between the roller and the peghead, and means for securing the rollers to the rod, such that when strings are pressed down above the string nut and released they will easily slide back to their original position, thereby allowing the playing of special effects above the fretboard.
