D'AddarioNexxus 360 Rechargeable Guitar Tuner - Clip On Guitar Tuner - Acoustic Guitar Tuner - Electric Guitar Tuner - 24 Hours of Tuning Time per Charge - Rotates 360-degrees

I have owned many clip on tuners over the years and this is one of my favorites. It is very accurate and responds very quickly. It is small, discreet and light but with a clear, bright screen. It has a calibration option and the tuner remembers the last calibration when you switch it off and back on. You can recharge it and the battery seems to last for long.

Really great. For sure! These are small and compact but well designed and made. Simple to use. Bright. Works well in actual use and it stays charged a long time. I like these by far better than my other tuners and better than even my p#s rechargeable tuner of similar design. This is better. Not usb-c. Usb-c would be much superior in my view and would be recommended to the manufacturer as an upgrade. Nevertheless this is the best rechargeable tuner.Update:9/30/2024This tuner is 'extra' nice. Extra nice because it stays on active for a long time and a player can actually monitor/check notes and chords with decent accuracy while continuing to play for a while. It definitely stays on way longer than minimally necessary when activated. This is good because it continues to do its job longer than most tuners. The easy rechargability is most welcome instead of ubiquitous batteries.

great accuracy, visibility, and ease of use. the hinge and swivel make it so i can always turn the face to be able to see it upright and head on no matter where i need to clip it on the headstock. the display is crisp and bright. the main reason i got it was for the rechargeable battery because i was tired of buying batteries for my snarks but i’ve had this over a year and the battery is still green!

Edited: After the replacement arrived, it appears to work much better. It is much more responsive and no longer gets stuck on "C". Screen is plenty bright and it's much smaller than the Snark, which is nice for a uke. I love that I can fold it down and just put my instrument in it's case with it still attached if I'm in a hurry. Rotates 360 which is nice as well.It would work partially until I tuned the C string on a ukulele. Then no matter what note was played it keep staying it was "C". Item was fully charged. I sent a replacement request to amazon so I will see if the second works better and maybe this one was just defective. Screen is easy to read and adjust to different angles. I really do like this one, but I'll end up going back to a Snark Supertight if the second one doesn't work.

I've had a lot of tuners (snarks, microtuners, etc, both battery and rechargeable) and so far this is the best by far. Small size but big display, very bright even in sunlight, secure and protected clamp, rotate well for easy visibility, controls are simple and right in the front for easy access, battery usage display, quick and accurate. Worth the few extra bucks.

$30 for one is a little steep for this tuner, but it works great, fast, accurate, and rechargeable. I would probably order the USB-C version of this if they would ever release it. I do understand it is probably unnecessary, and the Micro USB charging is just fine for such a small device. I will try to compare my other tuners before I finally decided to order the Nexxus 360 tuner.Micro Headstock Tuner (Clip-On version) - My very first tuner from D'addario. Solid and accurate. It's probably because the mini clip is tightly attached to the headstock without any wiggle.Micro Headstock Tuner(universal version) - I ordered 2, came defective due to over sensitivity. Ordered 2 more as replacement, defective and overly sensitive to the point of displaying random letters on its own. It is probably the universal clip, or an defective batch. I really did not like the universal clip mainly because the way it clips, one side is not flat enough to grab tightly onto the headstockNexxus 360 Rechargeable Guitar Tuner - It is a perfect fit on my Classical Guitars headstock, extremely accurate, and fast. However, on my Acoustic Guitar, due to the headstock being thinner, the clip does wiggle to the left or right if a little pressure is applied, which is very annoying.The pros of this tuner out weighs the cons in terms of quality. Maybe I'll try the Micro Sound hole tuner later on, but for now if you want a small portable tuner, the Nexxus 360 or the Micro headstock tuner (clip on version) will do just fine.

I really like this tuner. I'm surprised at how long the battery lasts. I've had it for several months and have only recharged it a couple of times. I do turn it off when I'm not tuning, but still. It's easy to read even though it is smaller than other brands I've tried.

Tiny with a really nice and bright display, and the rechargeable battery is great. I use it on my classical guitars, the clip is just barely wide enough for the thicker headstock but it fits and it stays in position. I've only used it in standard tuning so far but it picks up all the strings very easily and seems accurate. Swivels in any direction so you always have a good view of it. Great value for money.
