Der Filzkopf unterst\u00fctzt einen volumin\u00f6sen Klang und macht den Schl\u00e4gel zu einer vielseitigen Wahl f\u00fcr die Bassdrum.  Der 340 mm lange Stiel wird aus Buche gefertigt und lackiert. Mit einem Durchmesser von 25 mm bietet er einen angenehm kr\u00e4ftigen Griff und eine robuste Konstruktion. Gleichzeitig er\u00f6ffnet der Holzstiel eine zus\u00e4tzliche Spielm\u00f6glichkeit: Er kann auch perkussiv auf den Rims eingesetzt werden und erweitert damit das klangliche Spektrum.  Der scheibenf\u00f6rmige Filzkopf besitzt einen Durchmesser von 40 mm und eine mittlere H\u00e4rte. Damit kombiniert der BM 439 einen vollen Bassdrum-Klang mit einer stabilen, klassischen Bauweise und zus\u00e4tzlichen M\u00f6glichkeiten f\u00fcr perkussive Akzente.",
