The new Malletech Escape Ten Series is a collection of keyboard mallets purpose-built for ensemble playing. Designed and optimized over several years in chamber settings from duos to large ensembles, each model is “tuned” to speak its special voice through the musical texture. Adjacent models, though close in Malletech hardness rating (10,12,14,16), have distinct contact and timbral characters so that 10s and 12s can be distinguished even when playing in the same range.
