Whether you play acoustic or electronic cymbals, you'll be amazed at all the Aquarian Cymbal Spring can do for your performances. The patented spring bottom allows cymbals to move unencumbered, minimizing keyholing and stand vibrations for longer life and cleaner sustain. They also give electronic cymbals a more lifelike sway and prevent spinning, keeping cymbal zones in the sweet spot at all times. Aquarian Cymbal Springs even give stripped stands a new lease on life, clamping over the worn threads and replacing the cup washer, felts, and wing nut entirely.
