The Aquarian inHEAD trigger pack includes a dual-zone snare trigger system built into a real 2-ply Aquarian head, along with the popular kickZONE external bass drum trigger. These let you blend acoustic drums with electronic samples from a drum module or laptop with no effect on your playing. The included inBOX power supply mounts to your snare and lets you adjust sensitivity on the fly. This is useful when you only want to trigger samples with your backbeats one moment, but capture ghost notes the next.
