Testing the Limits: How Strong is a Guitar Neck?
How Strong is a Guitar Neck The strength of a guitar neck has long been a topic of debate among enthusiasts. Can it withstand the tension of strings, or will it snap under pressure?

Henry and Julius Grossman started what became Grover in Cleveland, Ohio, in 1922 as wholesalers of instrument accessories, and the company only took the Grover name in 1952 after buying out A. D. Grover & Son, an older firm that had already built a reputation for machine heads on fretted instruments and violins. Grover's enclosed Rotomatic tuners, developed not long after, became the reference point for smooth, precise tuning stability and remain the default upgrade path for anyone unhappy with their guitar's stock tuners. The company also owns Trophy Music and still makes the Flutophone, a children's instrument that's sold in the tens of millions. We mostly cover Grover as the hardware fitted to guitars we're reviewing. Here's what we've written.

Tuners, principally. Grover Musical Products designs, imports and distributes machine heads for guitars, basses, banjos, mandolins, dulcimers and ukuleles, along with violin pegs and banjo bridges, from its base in Cleveland, Ohio.
The enclosed-gear tuner fitted as standard to a great many guitars, including much of Gibson's output over the decades. It is probably the single most common aftermarket tuner in the world, and the locking Rotomatic is the modern version for players who change strings often.
The company took its present name in 1952, when it acquired Grover Accessories Co. — formerly A. & D. Grover & Son — following the death of Walter Grover. It has since absorbed four other companies as divisions: Trophy Music, Duplex Percussion Accessories, Grossman Music and The Clevelander Drum Company.
Rotomatics use a larger post hole than vintage-style tuners, so fitting them to a guitar built for Kluson-style pegs usually needs conversion bushings or reaming. Grover also makes vintage-size Sta-Tite models for exactly that reason — match the post size before you buy.
