I have numerous guitar tuners and I have to say that when I reviewed the Otopaku Clip-On Tuner, I was a bit impressed by the accuracy and I also like the fact that they included two CR2032 batteries.
The tuner can tune your chromatic, guitar, bass, violin and ukulele. The tuner can clip on the head of your guitar/uke and unlike other guitar tuners, this one has an LCD color display which is bigger than the usual tuners.
The tuner also features easy dual-hinged clip and Tuning Range B0 – B7; A440 calibration.
On the front is the power button and you can use the same button to cycle to whichever instrument you want to tune.
The tuner has an auto shut-off when not being used as well.
Overall, I have to say the that the Otopaku Clip-On Tuner worked well and tuning my guitar and ukulele worked perfect. I didn’t have any significant problems and found it straightforward and simple to use. And at under $14, it’s definitely worth considering.
