A Glass Slide Designed for Smooth Touch and Expressive Sound
The D'Addario Planet Waves Glass Slide Large is a glass bottleneck designed to provide a smooth, precise, and snag-free playing experience. Thanks to its borosilicate glass, it combines strength and sliding comfort, ideal for executing vibratos, slides, and controlled attacks in blues, rock, country, or ambient styles.
Each bottleneck is heat-treated to achieve perfectly smooth edges and a uniform finish. The result: less unwanted noise, better string control, and a more consistent musical response, whether you play in standard tuning or open tuning.
4 mm Thickness: Warmth, Power, and Sustain Delivered
With its 4 mm thickness, this bottleneck promotes a full and singing tone while enhancing sustain. The mass of the slide helps the note "speak" longer, with the beautiful roundness typical of glass: perfect for expressive melodic lines and nuanced playing.
Available in several sizes (S, M, L), this Large model is especially suited for guitarists who want a slide with a larger inner diameter while maintaining a classic "bottleneck" shape for comfort and precision.
