Nickel plated-brass Rock Slides are a great combination of tone and string feel. They are slippery - like glass - but have the weight and the long sustain of brass. Unlike the polished brass slides, they remain slippery for a very, very long time.
RockSlide Guitar Slides
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 the first RockSlide guitar slide. Carving a solid brass rod using CNC technology gave RockSlide the freedom to create its signature tapered interior, finger rest and knuckle cutaway. After 14+ years RockSlide is still family owned and made in USA.
