Thank you for viewing! Please bear with me a little longer (^^) An ethnic cover frame made of void tube, slightly smaller than the head, is gently secured with rope. This is a 29-inch double-headed frame drum, 79 centimeters! By pulling the tension diagonally downwards instead of at right angles, stress on the head is reduced. The edge sound is crisp, and the deep bass resonates in your stomach. Both the front and back are new YAMAHA timpani heads, market value 25,000 yen or more. Two of those are used!! I got them cheap this time, but please search for the price. There are 12 aluminum molded lugs. Here are the specs! Frame Timpani 29 inches Playing surface: YAMAHA timpani head Diameter: 29 inches, approximately 78 centimeters Frame diameter: approximately 74 centimeters Frame: Void tube, 5 centimeters thick Four more drums are scheduled to be listed. Get them early! Shipping is included for this large item. Thank you for your understanding of the price!!
