Why did The Rock Slide® bother to make a guitar slide in the first place? As players, they were fed up with the same-old selection of bottles and pipes that were available. In 1999, the slide industry was forever changed with the introduction of their first guitar slide. Carving solid brass rod using CNC technology gave them the freedom to create their signature tapered interior, finger rest and knuckle cutaway. After 14+ years they are still family owned and made in USA.
