Moulded Glass Rock Slides are individually hand moulded by master lampworkers.  These have all the same features as our brass Rock Slide® 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.  Because of our unique tapered interior design they do have enough mass to light up your acoustic.

The Moulded Glass Rock Slide also has very thick walls because of the internal taper, in fact, the walls at the opening are 4mm and 6-8mm thick at the fingertip end. That’s about twice the thickness of a typical heavy wall glass slide at the end. A baseball bat has a sweet spot for hitting a home run, The Rock Slide® has a sweet spot too. While it is thick enough everywhere to light up the strings, the extra thick end almost acts as a gain knob which helps bring out the low notes, and makes for killer lead playing.

Frosty Glass slides are exactly the same as the standard moulded glass slides but with a little more grit and string noise.  They are still quite smooth, just rough enough for a little extra growl with vibrato.
