Adams Parabolic Copper Bowls project fully, cleanly, and clearly, and are polished to a brilliant shine. Adams Universal Timpani are designed for all concert and education uses. An easy instrument to operate, the pedal mechanism can be silently locked into place to pinpoint any note, and the fine tuner can be used for further adjustment. Universal Timpani feature legs that are adjustable to the player’s height while seated, and easily retract into the kettle for transport.
