Grover

Grover Musical Products, Inc., is an Ohio based American company that designs, imports, and distributes stringed instrument tuners (machine heads) for guitars, bass guitars, banjos, mandolins, dulcimers, ukuleles, and other instruments. Grover also imports and distributes tuning pegs for violins and bridges for five-string and tenor banjos. The company has four divisions—former companies that they acquired: Trophy Music Co., Duplex Percussion Accessories, Grossman Music Corporation, and The Clevelander Drum Company. Grover adopted its name in 1952 when it acquired Grover Accessories Co. (formerly A. D. Grover & Son), following the death of Walter Grover.
