Handcrafted Glass Guitar Slides, Tone Bars, & Picks

Supporting slide guitar players with premium glass guitar slides, each born of fire and crafted to ignite your tone and style.

We use modern glassblowing techniques to create handcrafted tapered interior guitar slides, brass-core glass tone bars, and glass picks. 

We also offer custom-sized glass guitar slides, tailored to fit your unique finger and playing style, ensuring the perfect slide for every player.

Silica Sound slides are the original glass guitar slide made with a tapered interior, since 2003. Made in San Francisco, CA.
