Independent shopping perspective
Grover’s nickel Planetary Metal Button tuning pegs combine a 4:1 ratio with lubricated internal gears for smooth, accurate string-tension adjustments. The internal mechanism is sealed to protect its components from the elements. They are made for instruments with 3/8-inch peg holes, so that measurement is the key fit check before installation. Their lightweight construction keeps the focus on a direct, precise tuning workflow for practice or performance.
