D'Addario PW-CT-12 NS Micro Headstock Tuner

I use these tuners for my bass guitars. They are accurate and work very well for my bass instruments. I never take them off as they are so small and discreet. The letters are easy to see, and can be viewed from different angles. Purchased one as a gift for a friend who plays mandolin and is he is delighted with the ease of use and the size of the tuner. I have been using mine for over 6 months and have not had to change the battery yet. Would highly recommend this tuner to fellow musicians.

Excellent quality and has a good display that you can actually read outside in the sun. I love how the display can be reversed or inverted to fit in any direction. Easy to use and give an accurate reading. Discrete in use and doesn't look out of place. Perfect for both right handed and left handed players. I expected it to come loose and fall off but fitted correctly it is rock solid and I had no issues using it in a live situation. Instructions say not to leave it on all of the time as it may cause finish damage in 'expensive' guitars (think Nitro/Rickenbacker). Overall I am very pleased with this tuner. Prices vary considerably from different sellers so shop around (anywhere between £19 and £45 at the time of writing).

These things are tiny, so tiny in fact that you can pretty much leave it on your guitar all the time. I checked the tuning against other clip-on tuners and devices and it's pretty much spot no matter what position on the headstock it's placed. It's small enough to almost go almost unnoticed when fitted to the back of the headstock too. They are a little flimsy however, and not the most robust of tuners, but this is largely down to their very diminutive size. The reaction time I found quite adequate and the simple coloured display is easy to see although not the brightest. The only thing I'd be a little bit wary of is the way it fits on the headstock, which is achieved with a very small push-in clamp. This seems to have preset positions so you have to choose one that is closest to you headstock thickness then push it on. If you headstock is an unusual thickness, not perfectly flat, or has a chamfered edge this may not fit properly. It's also better to choose a setting slightly smaller than your neck thickness then push it on more firmly. If its not in good contact with the neck it won't pick up the harmonics properly and work correctly so take some time to get a good fit. This works really well on Strat type head stocks where it can be fitted just above he nut, but on my Gibson 339 and Les Paul it had to be fitted to the end of the end stock. It's stayed in placed even when placing and removing the guitar from the case but wouldn't take much of a knock to remove it and its small enough to be easily lost. It's not suitable for gigging, but for home use its great. I've ordered a couple more so I can leave one on each guitar.

I have never been keen on cumbersome and fragile clip-on tuners but this is an excellent product. Very discreet, well designed, extremely sensitive and very accurate (tested on acoustic guitar and mandolin). Build quality is good, the ratchet clamp is neat and the non-slip surfaces grip well. I had no difficulty in seeing the changes on the colour display without needing my reading spectacles. I like the fact that it remembers which way the screen orientation is set after power off and the visual metronome is useful. The larger power button is near the display end so it is easy to feel without needing to see it. After power-up, the base frequency is briefly displayed but, usefully, there is a three or four second delay before you can change it; setting it by accident is extremely unlikely. However, if you do make a change, it does not reset to 440 on power-down so it is worth checking at power-up (just in case some joker has decided to set it for you). I needed to use a small screwdriver to loosen one side of the battery cover but I much prefer this to having it fall off in the dark. You might be aware that some strings can sound a little flat if they are not plucked at full playing volume and this tuner is sensitive enough to show this tendency. On a properly tuned string with both bars on, the left bar will tend to go off if you hit the string very hard. The percentage change is tiny but this sharpening effect is properly detected and you can correct for it if you prefer. This tuner was recommended to me by a professional musician and, at under £12.00, I ordered four without hesitation. If you appreciate great design, and the sound of properly tuned instruments, I'm sure you will be impressed.

Accurate tuner. Small enough to be able to leave it on the guitar at all times

purchased this product based on the reviews, and I must say, it's truly a little marvel. While I knew it was small, I didn't anticipate it being this tiny! Nonetheless, it's essential for musicians.

Absolutely wonderful

Great product.... love it💖 I'll buy again.

El afinador D’Addario Micro es un accesorio compacto y práctico que he estado usando recientemente, y aquí comparto mi experiencia con él. Lo que me ha gustado: 1. Tamaño compacto: Es increíblemente pequeño y discreto. Apenas se nota cuando está colocado en la guitarra, lo que lo hace perfecto para presentaciones en vivo o sesiones de práctica sin llamar la atención. 2. Precisión: A pesar de su tamaño, el afinador es sorprendentemente preciso. Detecta las notas rápidamente y sin errores, incluso en ambientes con ruido moderado. 3. Pantalla clara: La pantalla LED es brillante y fácil de leer, incluso en condiciones de poca luz, lo que es ideal para escenarios oscuros. 4. Fácil instalación: Se fija de manera segura al clavijero sin dañar el instrumento, y es fácil de ajustar para una buena visibilidad. 5. Autonomía: Tiene una excelente duración de batería, lo que significa menos preocupaciones por cambiarla frecuentemente. Lo que no me ha gustado: 1. Visibilidad limitada desde algunos ángulos: Aunque la pantalla es brillante, el tamaño pequeño puede hacer que sea difícil de leer desde ciertos ángulos, especialmente si no está perfectamente alineado. 2. Botón pequeño: El botón de encendido/apagado es algo diminuto y puede ser complicado de manejar para personas con manos grandes o si estás en una situación apresurada. 3. Sensibilidad en cuerdas graves: En ocasiones, puede tardar un poco más en captar las notas graves de una guitarra flamenca o acústica, aunque no es un problema mayor.

i purchased this almost 10 years ago still works perfectly without any issue
