D'Addario NS Micro Headstock Tuner 2-Pack

I broke a Fender tuner that I had to remove every time I put a guitar back in the case. These are small enough that they can stay on and cheap that I don't care if I break or lose them

These tuners are small, discreet, and accurate. I have them on all of my guitars

I like how the tuner can be hidden behind the headstock. I can be seen well when indoors but is a little bit more difficult in sunlight, typical for tuners. I use this tuner on both guitars and basses and tuning the higher notes is quick. However tuning the low E on the bass is a problem. I would probably tune with another tuner before I start a set and just use this to check during the set.

Very easy to use and flexible for mounting positions and ease of line of sight!

There are so many electronic tuners on the market, it's difficult to narrow the field. Many have "polarized" reviews. A lot of good, along with numerous negative reviews (keeping in mind that consumer electronics always have a certain number of defective units). I bought these in a 2 pack, around 10 dollars each (My first digital clip on tuners). I like several things about them. First, they don't look like a tree growing out of your headstock. In other words, they are unobtrusive. Secondly. they aren't of the design like Snark and others that have obvious weak points (the "neck" that attaches the body to the clip), that you know will eventually break (read the negative reviews). The locking stepped clip works very well. Third, the display not only physically rotates on the clip mechanism, the color LCD (LED?) display can be rotated electronically to 1 of 4 orientations, very much like you can do with photos on your cell phone. Fourth, they are quite sensitive, much more than my old style Fender vu meter style tuners, which are getting finnicky. Fifth, You can quickly mount them and tune, no fiddling with patch cords and plugging and unplugging the cord. You can leave them in place, with the display on the back side of your head stock, or wherever you prefer. Sixth, they work equally well on bass and guitars. If there is any con, it's the fact that they are quite small, which of course is also an advantage. It took some trial and error to find a good spot on my bass that allowed clear viewing, but that's a minor thing. The display is quite small, but bright and easy enough to read, even for me, a far sighted over the hill guy. I can't speak as to longevity or battery consumption as I have only had them a few weeks. but another positive is that they utilize C2032 button cells, a common and relatively inexpensive size. You shouldn't have to make a special trip to the specialty battery store when you need to replace them.

I keep one clipped to my acoustic guitar and one on my PJ bass. It is easy to clip them to the underside of the headstock - easy to see when needed and not in the way of the tuning pegs. Almost like they are built in!
