The Rhythm Tech RT7400 Hat Trick Nickel mounts on your hi-hat pull rod to produce a bright, projecting tambourine sound. Its light weight and small diameter allow intricate patterns to be played without altering the feel of the hi-hat. Features eight pairs of nickel jingles.The tough all-steel frame has a black, powder coat finish. A low profile mount and wing screw takes up little space on the pull rod and make it fast and easy to remove the instrument.
