Daddario PW-CT-12 Micro Headstock Tuner

This is a very good and also a very affordable micro size tuner, suitable for many different instruments. Due to the low price I have on of these on practically every guitar I own, so I never have to look for a tuner, cause it's already there! Placing is almost never a problem, it is very discrete when placed on the back of a head stock. Display is simple but to the point, it shows you what you need. I use it on everything from acoustic and electric guitars to bowed instruments and folk music style plucked instruments. It triggers surprisingly well even on lower tunings, I use it all the way down to a low G (9 semitones below a standard guitar bottom E) on my long scale folk music style 12-string guitar. The only downside from my point of view is that the battery life is a tad short compared to other micro tuners, though still not over all bad. I've also found that when the tuner signals low battery, it still runs a decent amount of time after that.

This tuner is amazing, I use it for each one of my guitars. It's small, discrete and easy to use. Many of my friends did not even notice that I had a tuner on my headstock! The tuner is also very precise, I have had no issue with it tuning falsely. The only issues I've experienced is quality-related. It is a cheap product, and it sometimes shows with the backlight glitching out, a battery indicator that almost always show a drained battery and an often difficult (in one tuner I got, close to impossible) to remove battery latch. But none of these complaints will keep me from recommending this tuner. You get what you pay for, but in all the right areas.
