Yamaha TP-7300R Series Professional Timpani 23 in.

High-end models with hammered copper bowls. Hammering increases the strength of the bowl material for crisp attack and powerful sound. This series is designed to satisfy the needs of advanced players. To bring out the very best qualities of the copper material used, bowl size, bearing edge shape (the edge that contacts the timpani head), the diameter of the aperture in the bottom of the bowl, and other details have been meticulously examined and refined to deliver the deepest, richest tone possible in combination with outstanding playability. Specially designed hammering machines faithfully simulate the hand hammering process while eliminating the unavoidable inconsistencies of handwork. The goal was not only to improve efficiency, but more importantly to recreate the technique of master craftsmen. The result is bowls that exude hand-made warmth. The PAC system allows pedal resistance to be adjusted while maintaining perfect pedal balance. A large knob makes adjustment easy too. Pedal spring and head tension are balanced so the set pitch is maintained even if the player removes his or her foot from the pedal. Pitch changes across the entire range are smooth and easy. A wide pitch range of approximately a minor sixth per inch has been achieved. The timpani frame does more than just support the bowl. It plays a significant role in sound quality as well. In addition to offering outstanding strength and operability, the frames are designed to a weight that contributes to optimum acoustic response. Large main casters are supplemented by a third caster below the pedal, allowing the instruments to glide smoothly and easily. The height of all casters can be adjusted over a 25mm range, allowing precise adjustments to the instrument height as well as head angle. The instruments can be ideally positioned for standing or seated playing, on any stage. Adjustment is carried out using the supplied tuning key or an appropriate allen wrench, and can be easily accomplished by one person. The main casters include a one-touch lock mechanism that contributes to fast, sure setup. In addition to the main caster lock mechanism an auxiliary brake has been added to the pedal caster. The player can engage the auxiliary brake to securely lock the caster and prevent movement of the instrument. Includes a tuning key and Remo Renaissance heads.
