We work with some of today's top drummers, and we have been fortunate to have their unique design ideas come to life with our Signature Series. Each model is designed to the exact specifications of the artist whose name they bear. The John JR Robinson signature model is a full 17 inch. in length with a diameter of .570 inch.. The oval bead and quick taper assist in creating bold sounds on cymbals & toms.
