Silica Sound, LLC is owned and operated by Chris Davidson, in San Francisco, CA.
Silica Sound started making glass guitar accessories in Eugene, Oregon in 2003. The lack of options for a good fitting glass slide drove Chris to use his craft in glassblowing to develop the slides you see today. During initial research & development, we found that the process of adding colored glass to the slide and then melting it in, inadvertently formed the snug-fitting tapered interior. Thus, the original glass guitar slide with a tapered interior was born. And with it, great tone.
