Our Comprehensive Buying Guide
If you are shopping around for guitar tuners, you will notice a name that pops up more often than most. 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. The way your instrument is designed dictates what kind of tuners you should get.

Furthermore, Grover offers many alternatives, so you might find a specific design adapted for acoustic and electric guitars and available in different sets. All you need to do is to observe the specs carefully so that you always pick the right design.
