Cympad Moderator Cymbal pads reduce cymbal volume and unwanted overtones, moderate sustain and increase articulation while providing all the benefits of Cympad's advanced cellular foam. Foam is better than felt - Cympad's advanced, premium-grade, cellular foam is consistent in size, thickness and density - allowing Cympad cymal pads to conform to the shape and size of each cymbal while providing more natural cymbal support. Available in 6 sizes, Moderators offer a full spectrum of options for incremental control of cymbal sound in a variety of rehearsal, recording and performance applications. Moderators are highly recommended for practice rooms and teaching studios, too.
