Add a touch of custom color and professional ergonomics to your tone. The Rock Slide® Medium Sapphire Glass is a precision-engineered tool individually hand-moulded by master lampworkers. Featuring a stunning, deep sapphire blue hue, this slide offers the warm, clear character of glass with the patented comfort features that have made The Rock Slide an industry standard.

Now available at Haggerty’s Music, this Medium (M) model is specifically designed for players with a ring size of 9–11. It fits the ring finger comfortably for most players but can also provide full six-string coverage when worn on the pinky by those with larger fingers.

The Rock Slide Difference: Form Meets Function

While traditional glass slides are often simple, straight tubes that wobble, the GRS-MS is "carved" to fit the human hand for a more natural playing experience.

• Tapered Interior (Zero Wobble): Most slides are only snug at the knuckle. This slide features a tapered interiorthat maintains a snug feel all the way down your finger, providing immediate stability and control.
• Massive Sustain with Thicker Walls: Thanks to the internal taper, these slides have significantly more mass than a standard glass tube. This extra weight acts like a "gain knob," giving you the sustain needed to "light up" an acoustic while remaining fast enough to "cook" on an electric guitar.
• Patented Knuckle Cutaway: The unique notch at the base allows you to bend your finger naturally. This ensures you maintain the mobility needed for fretting chords and complex licks without the slide pinching or restricting your movement.
• Integrated Finger Rest: A dedicated flat surface on the side provides extra leverage and a stable spot for your neighboring finger, allowing for much more expressive and controlled vibrato.
• Hand-Moulded Quality: Every Sapphire Rock Slide is individually crafted for a mirror-smooth, frictionless playing surface, ensuring noise-free glides across your strings.
