The ddrum Red Shot Bass Drum Trigger detects dynamics in a very realistic way, thanks to the patented transducer solution-a must for any drummer. ddrum Red Shot triggers use a specially designed transducer that is softly pressed against the drumhead to prevent any damping effect. And Red Shot triggers are extremely easy to use and mount: just remove one tension screw, apply the trigger, and put the screw back on again. No adhesive required. Features a 1/4" jack for connection to a ddrumAT, ddrum3, or ddrum4 sound module.
