The "Drumballmallet series" gong rubber/singing bowl mallet/drum mallet is one of the first inventions of TTE Konklang ®. There is this series at the moment in Ø approx. 1,57, approx. 1,97 inch and approx. 2,36 inch. The surface is enroughed and a certain sound excitement in the gong in at least 3 different timbre spectra. The spectrum extending overtone sectors are also accessible with these products with the "Vario OTG 5". The material is extremely loadable. A "hot grating" of the surface the India rubber recipe, with the most intensive gong rubbing, is easily possible. Smaller or even bigger India rubber heads from this material are not to be made, because a disagreeable squeak noise arises as an accompanying effect. The Drumrubber mallet India rubber heads can be also drummed "hotly", i.e. selective big warm development are well taken by the material. The India rubber recipe is comparable with the rubber of a normal tyre which is suited for higher speeds well.
