The Roland RT-10S dual snare drum trigger is ultra-sensitive and about 10% smaller than its predecessor. Supports separate head/rim dual triggering. Easier to position and more discrete. Features the latest trigger-sensing technology for improved response. Easily attaches to either triple-flanged or die-cast acoustic tom hoops. Can be used with mesh heads as well as regular acoustic drumheads. Add RT-10T Acoustic Tom Triggers and the RT-10K Kick Trigger (sold separately and shown in the box of recommended products) to the RT-10S and trigger your whole set.
