Rogers Dynasonic C.O.B 1960s snare drum. This Dynasonic snare drum is in very good condition and looks as good as it sounds. The heavy duty chrome over brass (C.O.B.) design locks the sound of this snare drum right down. This drum sounds great from jazz to hard rock. The badge is missing, and the heads are like new. The throw and muffler are in great working condition and function smoothly!
