Star Singer Guitar Slides are handcrafted in Glastonbury, UK. A special process is used to break the glaze, giving each slide its own unique crackle appearance. A high-gloss finish creates a smooth surface that allows for a pleasant, quiet sliding experience. These slides are fired at over 1200°C and are very durable. Their sound falls between that of glass and metal slides: warm and clear. Design: Emerald Hollow short, height: 45 mm, inner diameter: 19 mm, wall thickness: 4.5 mm.
