For over a century, Grover has maintained the tuning on some of the world's finest instruments. As early as the end of the 19th century, Grover produced the first tuning machines for guitar and banjo. Soon the range was expanded to include tuning machines for bass and pedal steel guitars, mandolins, dulcimer, ukuleles and violins. Despite all the changes in the music business, the Grover brand remains a constant, standing for the best available products on instruments from various manufacturers. The company from Cleveland, Ohio developed technological breakthroughs such as the world's first permanently lubricated tuning machine heads - and is constantly expanding its product range with clever accessories for retrofitting and repair.
