Elevate your slide playing with the Moulded Glass Rock Slide – Medium, the perfect fusion of ergonomic design, crystal-clear tone, and handcrafted quality. Individually hand-moulded in the USA by expert lampworkers, this premium glass slide features all the legendary comfort and control of our brass Rock Slides®, now in a lighter, faster glass version.

Designed with a tapered interior, Knuckle Cut, and Finger Rest, this medium slide (19.5mm x 60mm) fits ring sizes 8–10.5 and offers a snug, balanced feel that adapts to your finger for enhanced control and reduced fatigue. Despite its lighter weight, the unique taper adds just enough mass to project beautifully on both electric and acoustic guitars.

Slightly longer than its brass counterpart, the Moulded Glass Rock Slide provides smooth movement and bright, expressive tone that makes solos sing and chords shimmer.
