Pressure meter/drum tuner that quickly and precisely tunes all drums by accurately measuring drumhead tension, not tension rod torque. Tension rod torque can be used to tell when the bolt is over tightened to prevent thread damage, but is not accurate for drum tuning because of the difference in screw tolerances, plating, corrosion and thread wear. This drum tuner measures drumhead tension directly from the drumhead, allowing precise and faster tuning of the drums. It features the DrumDial Edge Gage that is easy-to-read, a locking bezel with moveable locators for easy marking of the tuning range, a lug back for improved handling and a soft foam lined box for tuner protection.
