That name is Grover and belongs to a manufacturer that has built a solid reputation over the years. This buying guide is intended to help you choose the best Grover tuners for your musical instrument. Follow these guidelines, and you cannot go wrong.
There are separate models for acoustic and electric guitars
The first thing you must bear in mind is that there are Grover acoustic guitar tuners and sets created for electric instruments. Those shouldn’t be used interchangeably for obvious reasons.
