Designed for streamlined setup for those who want to explore hybrid acoustic/electronic drumming, the RT-30H Single 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. Its 1/4" trigger output is side-mounted for cable management. A stereo TRS cable is included.
