Musicians have long been known to use actual tool sockets for guitar playing because the 12-star interior grip keeps the slide locked on your finger. Tool sockets have a drawback thoughthey are too heavy on one end. Clayton corrected this feature by equalizing the weight on each end of the guitar slide, which allows for consistent balance, weight, and tone. To enhance the slide even more, Clayton has made it in brass for enhanced quality and sustainability of tone. A cut-out relief has also been added for additional comfort during play. Truly a superb piece of craftsmanship.
