About this Tuner

This tuner conveniently clips onto the headstock of you Guitar, Violin, Bass, or any stringed instrument! It works by vibration so won't be affected by background noise.  The coloured display makes it easy to read in a light or dark environment. Once you are tuned up, switch it into metronome mode and play along.  It's always within reach and out of the way.

Important: The metronome is a light based system.  It does not make any noise.  The metronome works visually only.

An awful cheap tuner

By: on 27 July 2021
I’m sorry I bought this. It’s a poor design, doesn’t work properly and has awful instructions. I wouldn’t recommend it.

Mine doesn’t really work

I’m a huge fan of Joyo and Artist. But this tuner hasn’t worked for me from day 1. With a brand new battery, the readout inexplicably dims until it’s practically black - only to come back on another time - then repeat. As to its accuracy as a tuner, it’s not good. I kept trying unsuccessfully to use it on various guitars until 2 different mates (both experienced guitarists) tried it on their guitars, then put it away in exasperation. My mistake was not returning this tuner immediately: I thought it was just me doing something wrong (first headstock tuner for me). It’s sad really - it looked good on paper. But mine really isn’t. Btw - it looks/feels cheap: it’s made of light, thin plastic that’s more like something you find on a toy rather than a proper instrument accessory. Sorry Joyo and Artist...

Excellent tuner, works very well - silent metronome is handy when trying to keep time on the fly
