Highly-regarded as one of the most innovative percussion makers in the world, Pete Engelhart’s visionary instruments ? like the Gon Bops 3 Bell Triangle ? are used by Terry Bozzio, Alex Acuna – and a whole host of other elite artists. Hand-welded from raw steel, no two bells are alike. All Pete Engelhart bells are equipped with patented Gon Bops V-Grip mounting system!
