Boss TU-10 Clip-On Chromatic Tuner

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.


  • Tuning Accuracy: ±1 cent
  • Tuning Range: C0 (16.35 Hz) to C8 (4,186 Hz)
  • Reference Pitch: A4 (436 to 445 Hz)
  • Tuning Modes: Cent display, Stream display
  • Display: “True color” LCD and monochrome reflection-display function
  • Power Supply: CR2032 lithium battery
  • Dimensions: 2-7/8" (73 mm) x 1-5/16" (33 mm) x 2-1/2" (62 mm)
  • Weight : 2 oz. (45 g)
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.
