Designed for streamlined setup for those who want to explore hybrid acoustic/electronic drumming, the RT-30HR Double Acoustic Drum Trigger from Roland attaches directly to your drum’s metal rim, employing a self-guiding mount that eliminates the need for mechanical adjustment once mounted. Its head sensor allows it to be used on toms and snare drums, and supports independent head and rim triggering. Its 1/4″ trigger output is side-mounted for cable management. A stereo TRS cable is included.
