John Tafoya Signauture Staccato Timpani Mallet with Bamboo Shaft (Pair). The TMB-5 Staccato Timpani Mallets by Grover Pro Percussion feature hand-selected bamboo shafts that are custom-lathed and finished using an exclusive 10-step process. This process provides a unique moisture seal which results in a superior, smooth feel. The custom finish further prevents the bamboo from drying out, which deters warping and splitting and increases the overall life of the shaft. Finally, the shafts are hand-paired to ensure proper balance and consistent diameters. Quality wool felts are hand-sewn over wood cores to provide a full tone with minimal contact sound.
