This new model is an expansion to the Rattan Series vibraphone mallets. The DM20 mallet, designed for Dan Moore, associate professor of music at The University of Iowa and member of the Britain Moore Duo, features a full tone mallet that sounds pleasing on both vibraphone and marimba. The Rattan Series Artist Models feature the same qualities as the existing rattan models - hard rubber mushroom shaped cores to create a full rich tone and warm fundamental and multi-ply cord for strength and durability, on our high quality, extra durable rattan handles.
