The Ultimate Percussion Wrench enables percussionists and drummers the ability to easily tighten or loosen wing nuts and tune their drums. Its compact, durable design combines a wing nut socket, a hexagon standard socket (perfect for tuning congas, bongos, timbales, and other percussion instruments), and a drum key to make the percussion wrench a truly all-in-one, multi-dimensional drummer's tool. Eliminates the need for using pliers which can damage your drums hardware! This all-in-one percussion tool is also great for tightening cow bells, wood blocks, claw clamps, equipment and cymbal stands, mounting racks, percussion stands, and more. Hand crafted from solid Stainless Steel. Endorsed by famed percussionist Karl Perazzo, drummer extraordinaire, Marvin "Smitty" Smith (Jay Leno), and the incomparable Thomas Lang. Includes one wrench. Approx. 2.5" x 3.75".
