It's unlike any other drum key on the market! The Protorq is a combination torque wrench and drum key that allows players to pre-select a tension level for tuning any drum, giving them a super fast way to tune. By using a thumb wheel with numeric settings, drummers quickly and accurately tune all of their drum lugs without under tightening or over tightening. The Protorq alerts a drummer when a lug has been sufficiently tightened.
