The dimpled brass jingles give the L174 a distinct crisp sound. The LP Cyclops Tambourine is the most ergonomically designed, comfortable and durable tambourine ever produced. Its unique patented shape has been designed especially for natural arm and wrist motions to offer greater playing ease in all situations. Rounded edges provide extra durability for drumstick hits. They have been found to last five-times longer than other tambourines. All LP Cyclops® Tambourines have a patented jingle pinning system that keeps the jingles in place.
