Unlike other drum tensioning systems, this drum tensioning system has no component directly involved with the tension and tuning of the drum head coming into contact with the shell of the drum. This drum tensioning (tuning) system tunes the drum in an industry standard fashion while greatly reducing the quantity of material in direct contact with the drum, and greatly reducing the area of holes drilled into a drum's shell. In addition, this system eliminates the need for springs, which are the cause of hum and vibration when drum sounds are amplified.
