The best guitar tuners for classical, electric and acoustic guitars in 2024

Posted on

Guitar tuners come in many different forms, each with their own set of strengths and weaknesses. As an audio engineer, record producer, and multi-instrumentalist, I have decades of experience playing the guitar

How we picked the best guitar tuners


Accurate pitch detection is the most important feature of any good guitar tuner, and almost all of the tuners on this list operate with a maximum margin of error of 1 percent. In other words, expect these tuners to provide pitch accuracy down to a tenth of a cent, or a thousandth of the distance between two notes. The only exception is my value pick, the Snark ST-8, which is a great tuner but has no published accuracy readings.


Although tuners are not the most expensive instruments available, they are still an essential piece of equipment for any guitarist. Therefore, it’s best to avoid underusing the tuner if you want a fast and accurate readout that won’t let you down in professional settings. This list includes some of the most reliable, powerful, and flexible options on the market that are priced within the reach of the average user.

Finally, the Roadie 3, my smart tuner, tunes my guitars automatically, so it’s in a class of its own.
