Why did The Rock Slide® bother to make a guitar slide in the first place? As players, we 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 our first guitar slide. Carving solid brass rod using CNC technology gave us the freedom to create our signature tapered interior, finger rest and knuckle cutaway. After 14+ years we are still family owned and made in USA.
