Get that fussy banjo head in perfect tune with the Drum Dial. The large, easy-to-read dial measures banjo head tension directly from the head for accurate tap-tuning. Drum Dial sits on the head, and the included edge guide ensures that it is always the same distance from the tension hoop for accurate reading. Comes with clear instructions and foam-padded cardboard box for storage. One year warranty. More effective and accurate than a torque wrench, which measures bracket tension.
