Code drum heads are purpose-built, designed by drummers for drummers. They have matched time honoured and trusted manufacturing techniques with up to date cutting edge technology to produce a new premium range of drum heads. All their heads use the highest quality PET polyester film, kept securely in place by Code's revolutionary Grip-Tight rim technology. This unique innovation features a deep, double-knurled solid steel core securely crimped by a high-quality aluminium rim, to ensure the head stays put while you play. It also allows the head to resonate freely, tune easily and super quick, and hold its tuning longer. Plus, all materials used to manufacture Code products are 100% recyclable. Code DNA series coated heads have a 10 mil single ply of high quality PET film that gives an old school warm sound with strong attack and medium sustain. DNA heads can be used as batter or reso heads. Full set of 3 tom heads, plus FREE DNA 14" Coated Snare Head! Oxygen Music is proud to stock a wide array of Code Drum products such as the CHDNACT101216.
