Moulded Glass Rock Slides are individually hand moulded in the USA by master lampworkers. These have all the same features as our brass Rock Slides® with the Knuckle Cut, Finger Rest and Tapered Interior. These fit almost exactly like their brass counterpart but are slightly longer. The main difference being that they are much lighter & faster so you can really cook with these on an electric guitar.
