“Don’t just take our word for it.”
“An absolute game-changer. After installing Grover tuners — both with a tuner and my ear, I can tell how accurate and consistent it is. And you can get very precise with how you tune your instrument, I would definitely recommend them!”
~ Santiago Calad, March 27, 2021
“They will last longer than you. Not cheap, but Rotomatics are simply the best!I immediately put a set of these into an old 1952 Les Paul I bought – in 1969! 52 years later they still work flawlessly.”
~ Les Ismour, April 14, 2021
“Grover tuners are about as close to perfect as you get and will compete with anything else on the market at a very reasonable price, so they get my 5 stars. I have used Grovers on a couple of my guitar builds and they never disappoint me.”
