SC-DB from Gibraltar. This drum key bit for standard power drills and electric drivers dramatically reduces the time it takes to swap heads and tune up. So whether you're refreshing an old set of heads or trying out a different sound in the studio, the SC-DB is a major investment in your quality of life. The SC-DB is especially useful for those of us drummers who are on our way up in years, as even a single head swap can be murder on the wrists and tendons. Whether you're a drummer, a drum tech, or a studio engineer, the Gibraltar SC-DB pays for itself in a single use.
