JOYOClip on Tuner Digital Electronic Tuner for Guitar, Bass, Ukulele, Violin, Mandolin, Banjo Acoustics Calibration Tuner (JT-09)

Perfect, second one. If you play many strings instruments you need this.

I compared this clip-on tuner to a well-known tuner of the brand name that rhymes with mark. On my acoustic guitar, I tuned one string at a time using the well-known tuner, then replaced it with the Joyo tuner. On five of the six strings, the Joyo tuner also showed the string was in tune. On the remaining string, the difference was negligible. Now, I'm not going to tell you that this tuner is good as the one that costs two to two-and-one-half as much. I have two of those other tuners and am pleased with them. But this is a good alternative for tuning up a guitar to play for fun.

Nice value, priced under $7.No instructions included, but it's simple, compact, and works well after a little trial-and-error.It slipped off the headstock a few times until I found a better spot on which to clamp it. No issues after that. Recommended.

I just started to learn guitar at home and needed a tuned guitar to practice on. This great device, for under $10 is just the ticket. My starter guitar is always in tune for my practice session. I purchased a second tuner as a gift for a friend who is more advanced guitar player. If if loose this one I definitely order another one.

I thought it would be good to have a tuner that wasn’t half the size of my hand, so I ordered it. It won’t stay on the headstock, plus it doesn’t do a good job of tuning.I downloaded a tuner from the App Store on my phone, and it works great. BTW, it free.

I got this for a violin. It is so small that it is difficult to find a place to clip it where it won't just fly off. I finally attached it to the chin rest, which seems to work. I would prefer a larger device.

Works well. Lights green when in tune. Be sure to set the setting to the proper instrument or chromatic tuner. If set to a guitar setting (for example) and you try to tune another instrument, it is just trying to get you tuned to the strings in standard guitar tuning and won't show other notes... which can be confusing! But it;s a great working affordable tuner!

There are so many tuners to purchase off of Amazon. It was hard to decide, so I opted to go with the least expensive option. I'm glad I did because it works great and came with a battery. Using the tuner is also intuitive. I'd buy this again!
