  • 2017.03: The Highest Rated Soundhole Tuner

Gearank Recommendation

The Rimpitch-C appeared on our now defunct recommended list for Soundhole Tuners from April 2017 until April 2018 when we stopped publishing that list.


It fits a wide range of acoustic guitars that have a round soundhole - you can measure the diameter of your soundhole and compare it to the specifications below to see if it will fit your guitar. It has a hook and rubber grip to prevent it from falling into your guitar.

It's designed for 6-string guitars and uses a piezo pickup to detect the notes.

One advantage it has over clip-on tuners is that it doesn't get in the way.

Importantly, it doesn't touch any of the bracing in your acoustic guitar - even where there is bracing very close to the soundhole.

This is the preferred soundhole tuner for many acoustic guitarists including those who play high-end instruments such as Collings, Martin, Gibson and Taylor.
