Solid Brass slides are favoured by acoustic & electric players alike for their comfortable weight & mass, combined with the unmistakable string overtones and ambience created by a metal slide. Solid brass provides a warmer and darker tone than chromed brass or chromed steel slides, but sounds brighter than glass or ceramic slides. Solid brass is a good choice for all styles of playing. The Dunlop 222 brass slides are made with medium wall thickness for maximum versatility. 19mm diameter / 60mm length. Acoustically tested.
