Calftone drumheads are a synthetic alternative to traditional calfskin. These heads embody the calfskin look and sound but with the consistency, fit, and tuning range made standard with Level 360 Technology. Calftone is made using a 12mil Mylar base blended with unique materials to produce warm, full, and rich tones. These heads bring out the best of a vintage kit and evoke a classic appearance and sound from modern drums. As an EQ4, a fixed internal overtone control ring helps focus the tonal response of the drum. Can be be used as both a batter and resonant head.
