Compact, holds on well on guitar headstock, and is accurate.

I bought 4 of these and haven't had a problem with any of them . They clamp on nice and snug without making a mark , batteries last a long time , if you turn them off every time you use them . Great little tuner !

Good little tuners more accurate than the snark tuners, BUT beware. I have a couple of these on my very expensive guitars. I left them on for a couple of weeks, and when I took them off they left a circle on my head stock where they had been - a mar in the finish that I couldn't buff off. That was a bummer! I recently gave away my snarks, and my Micros and started using KlIQ Ubertuners. They seem more accurate and faster. A little more expensive though.

I have been using this small and discreet friend for two years, excellent on stage, it can go behind the headstock and you can make a discreet look at the moment of tuning.

Great tuner - very small, but still visible. Doesn't look awkward when you leave it on while playing. I've had a couple going for several years now - still going strong.

Perfect for my little telecaster headstock. Super easy to use and very visible on a dimly lit stage. Also, if it's good enough for Mr. Jim Campilongo, it's good enough for me !

This tuner is very practical, easy to tune strings, easy to put it on, easy to put it off. After a year and two months first time I changed battery on tuner. Now it is as first day.

I was really thrilled at first to discover this little tuner that can be concealed behind the headstock of my guitar so that it's not visible to the audience when I'm on stage, but over time, I have found this tuner to be not so dependable - often not staying lit or reading the tuning properly. I have also found the clip falls apart or falls off too easily, and I have misplaced the tuner a number of times on a dark stage... Overall, I found myself going back to the older and larger Planet Waves clip on tuners that I purchased a few years ago.

I have used this on multiple guitars in multiple situations. It works well for quick,discreet tune ups and is the smallest headstock tuner I have ever (never) seen. I keep one on the headstock of my acoustic and it just lives there - in the case and on the stage. The visual metronome is a great addition. I have had to start tunes cold and just set this so I can get my foot tapping at the right beat before kicking off, but no distracting noise. I have to find just the right spot on the headstock to leave the tuner when using stands that hang the guitar from the headstock.

East to clip-on and read, and it delivers consistent results. I haven't changed the battery since I purchased it years ago.

I love this tuner so much. Small and working perfectly. But bad thing it is too small. I have lost 5-6 of this already.

This tuner makes my day so much better. So small, and does such a great job of tuning, especially if you get picky with it.

Work on every instrument, Accurate, and work for long time before you need to change batteris

I purchased this a couple months ago and it worked maybe 6 times before starting to blink constantly and not catching the notes. Tried a brand new battery.....no dice. This has only been used VERY gently in my living room. I have read elsewhere of this same blinking problem. Not worth the hassle for me to return it. I have other better ones.

Este afinador es muy util, además su pequeño tamaño hace que no sea molesto, y evita pasarlo a llevar con algo mas. Además, su pantalla puede configurarse para ser puesto tanto por frente, como por detras del clavijero.

I just got this item and I am very pleased with it. It's small (and that's a very good thing), it's accurate and very easy to use.

Not a bad tuner, small, out of sight but the darn thing ate up batteries just sitting in the case turned off. Contacted Planet Waves, they sent me a new unit but that too ate up batteries. I have larger tuners and they don't die that quickly. Would not recommend this tuner for that reason. Customer service was great...five stars for them.

This is an accurate, easy to read headstock tuner with a very low profile. I typically hate having a tuner on the headstock, but this one is so low profile that I don't mind having it up there even during a gig. Highly recommended!

I've tried a few of these and so have my friends. Love the size and the fact they can stay on your instrument even in the case, but they burn through batteries like mad and are horribly inaccurate, downright wonky, as soon as the battery gets a bit weak.

i work at a guitar store and i always keep one of these in my pocket. great size and quality, very handy .

This is the best and most compact tuner i have tryed, battery lasts a long time.

The best "micro" tuner I've ever tried! It's tiny, light weight, matches a lot of guitars, has the perfect screen and even a metronome (light)!

This tuner is my first foray into headstock tuners and I am more than pleased so far. When it came it was much smaller than I expected and happily so. I clipped it on my acoustic and immediately found the "sweet spot" for it and proceeded to tune it up without any problems. I then clipped it onto my Telecaster, near the nut and with the display under the headstock, and it worked perfectly.

The tuner is easy to use and easy to see. And very accurate

Works as advertised. I've never had an issue with it. Only thing I need is another couple of these for my other instruments.

I've had this tuner for over a year now and love it. Just ordered 3 more. Why? Because not only is it accurate, not only is it easy to see on a dark stage, it is also the smallest nearly invisible tuner out there. Korg has come out with a similar tuner but it is about twice the size of the NS Micro and still looks like an unwanted growth attached to your headstock.

I just popped these on a resonator and a Gibson J45 and they read frequency and tune EXCELLENTLY, but more importantly, they can stay ON the headstock in the case. I was constantly losing or having other types pop off or disappearing into the bowels of a gig bag or case. They are almost invisible on stage too, which is really nice on vintage instruments.

I now have two of these to go along with 2 Snark tuners and the other Planet Waves model. I find all three to tune very well and the reason I am moving over to the Mini is due to the low weight and ability to place closer to the nut it has less affect on the tone of the instrument. The larger tuners seem to take some of the overtones away leaving you with more fundamental.

I've now used the Planet Waves NS Mini Headstock Tuner for 7 months and I liked my first one so well I've since bought 2 more. I use them on my Martin HD-28V, Gibson F5 mandolin, and Gibson Les Paul. I've got a bunch of other tuners I don't use much any more because I love these so much. My first review said the clip seemed flimsy, but I've had no trouble with it.

Tunes accurately and quickly. Stays out of the way. Clip seems a bit flimsy, but what do you expect for $20?
