This all synthetic Clave Block will amaze you with its dynamic projection and cutting clarity. Injected molded so it's virtually indestructible, and the the solid colour will never chip, fade or peel. An integrated swiveling mount allows a diverse range of mounting opportunities. To compliment our PBL-20 Clave Block, we have added a higher and lower pitched version to offer you three tones. Pitched in thirds these blocks use CDV (Chamber Density Variation) Technology. This exclusive Pearl process allows all three blocks in the series to be the same dimensions, but still differ in pitch. The family of Pearl?s Clave Blocks will certainly find a home in all musical applications.
