Harnessing modern glassblowing technology for you to create brilliant music with the “Sound of Glass”.

Through creative innovation & quality craftsmanship, we strive to produce outstanding glass guitar slides and picks that compliment your sound and style. Silica Sound is the original handmade glass guitar slide made with a tapered fit, since 2003. Handcrafted in California, U.S.A.

Silica Sound glass guitar slides are handmade with a thickened end to promote a unique grip on the tip of your finger, as well as added mass for better sustain. They are unlike any other glass guitar slide in the way they feel, sound and look.

Unique Slides & Picks

These are one of a kind slides & picks that showcase modern glassworking techniques and artistic design. They are our high-end creations that will be the centerpiece of any guitar accessory or glass collection. Each piece is handblown by Chris Davidson in San Francisco, CA.
