The CymRing has been designed to fit tightly onto the sleeve UNDER or on TOP of the cymbal to provide the drummer with cymbal performance control. Cymbal Resonance Control - How long do you want the cymbal to ring? Do you want to take advantage of the higher tones as the cymbal was designed to produce? Lower tones tend to be there all the time, but the higher tones get lost in unnecessary dampening from alternative mounting products. This and Cymbal Movement Control are things you can sdjust with a CymRing. • MFSKU CYMRING • UPC 7908782898620
