Gearank Recommendation

The TU-10 appeared on our recommended list for Clip On Tuners from our first edition in March 2017 until April 2018 when it had been out-ranked by other tuners.


The Boss TU-10 is well regarded by guitarists for the strength and size of its clip which will fit onto even the largest headstocks.

It allows you to select your reference pitch and has a chromatic mode which allows for alternative tunings.

The display is bright and clear making it easy to see under stage lights.

Boss has a strong reputation, earned over decades, for producing robust tuners that stand the test of time which is why they're able to command higher prices than many of their competitors.

We were recommending the Boss TU-10 until April 2018 however due to a reduction in the size of our recommended list it didn't quite have high enough ratings to remain on the list which you can see at The Best Clip On Tuners.


I have this tuner and I have

I have this tuner and I have a real hard time tuning a bass guitar and it comes to worst when trying to intonate the instrument. I will be buying a Peterson strobo HD clip tuner.
