Developed in conjunction with designer Dave Gustafson, the SynchroNox system is a versatile drum trigger in/out package. A sensor on the drum head transmits each hit to a microprocessor, which in turn controls strips of blue led's, which flash brightly and rapidly, once for each hit. Includes a piezo sensor with rim-mounted guard, and shell-mounted battery pack (4 C batts.) and control box. The control box can switch the lights between sensor mode and constant-on mode. Also includes an auxiliary out for controlling any number of additional devices, such as NAO's F451 Flamethrower.
