OT12O Pocket Chromatic Orchestral Tuner

Does exactly what it says. Excellent bit of kit, easy to use. Tuning temperament feature was my reason for purchase. First rate.

I make and play ancient and Medieval musical instruments. Having recently made a recreation of a 3-stringed lute called a Timpan, mentioned in Irish and Welsh texts from the 9th to the 16th century, I wanted to tune it using the Pythagorean mode that was common across Europe during the 12th century heyday of the Timpan. Ditto with a couple of lyres, an Iranian setar and the horse-hair-strung harp that's my next project. It took some searching, but eventually I tracked down this neat little beasty from Korg, a company with a long and noble tradition of making quality electronic kit for musicians. The OT 120 did not disappoint. Having slotted in the provided batteries, a brief look at the instruction leaflet told me what buttons to push and lo, it's now set to Pythagorean tuning mode. Yay! It has excellent sensitivity, its internal mic easily picking up notes played close to it and providing good, clear feedback as strings are adjusted. The stand on the back seems a little flimsy. It works well so far, but I'll have to be careful with it. This is made easier by the nicely robust protective carrying case that comes with the tuner. This even has a strap for if you feel like hooking it to your belt. I probably won't, but it's a nice thought. It's much bigger than the average electronic tuner tends to be, but then it does more, being adjustable to a variety of tuning modes. Honestly, I'm delighted to have found a Pythagorean electronic tuner at all. It did take some searching. So, a really, really useful piece of kit for early musicians and kudos to Korg for producing it.

The display is very clear and the tuner has lots of helpful settings. I like that it has a needle rather than being wholly electronic and obviously it is also very accurate (+/- 1 cent). The only slight issue I have is the power switch does not really 'click' into place like you might expect and feels sometimes like I can only push it halfway between settings before it gets stuck. The settings wheel could also perhaps be a little more resistant as it can sometimes be moved around unintentionally as I am handling the tuner. It works well but I would have hoped a tuner of this price had more satisfying user input components.

I have not had this tuner very long yet, so I may update this review later on. But so far, this is the best tuner I've ever had... Very accurate. My previous tuner would only tune half my harp – it did not register the lighter strings. But this one does a marvellous job of tuning my entire harp to concert pitch. I am also currently using it while adjusting the semitone levers on my harp, and mean to use it for piano tuning. So stay tuned for an updated review when I have gotten more acquainted with it! So far, I recommend it.

I used this to tune my Rhodes piano. The analogue dial and sharp and flat LED's made it easy, especially at the top end where it was so fiddly seeing that the needle was almost there was good enough without striving for perfection. It had no problem with any of the 73 notes on the piano. I used it with the electronic input direct, not the microphone or the contact mike I bought. It even has different theoretical tunings built in. I cancelled the piano tuner. I didn't think I could have done it myself. Great piece of kit.

Excellent tuner...especially for guitar set ups , I used to have a much more expensive Peterson... I think this is much better :-)

There's not much to complain about with the Korg OT120, it's easy to use and stable. It has a full 8 octave (A0-C8) detection range, with a tuning accuracy to within ±1 cent, and Calibration a range from 349Hz to 499Hz. I like the dual analogue /digital display, which is easy to read and has a useful back light. The case is silver plastic with an Aluminium face, it looks flimsy but it's quite tough. The fold-out rest on the rear is really useful as it tilts the display so you can easily see it. I haven't tried the sound-back feature yet, but I imagine it could be quite a useful addition.

I bought this tuner to tune a wide range of instruments including, cello, guitar, leaver harp and Uilleann pipes. It handles all of these instruments well and for the price it is very good value for money.

Muy buena herramienta. He leído mucho a cerca de este aparato, e incluso me he documentado entorno a la marca, y creo que hoy por hoy en cuanto a profesionalidad, es uno de los mejores y más fieles afinadores que hoy en el mercado actualmente. Para mucho tipos y modelos de instrumentos, tanto de cuerda, como de viento. A pesar de todos los demás que hay en el mercado actual, que no son pocos. Saludos.

Un exelente producto en mi caso lo uso para mis guitarras electricas y la verdad es muy util para afinar y para octavar la guitarra por locque es muy bueno que tenga una aguja analogica. En cuanto a su construccion es de plastico y solo la caratula de alumunio pero se ve de buena calidad y viene con un estuche muy bonito para guardarlo el cual lo protege muy bienaparte de la señalizacion por aguja tiene su pantalla digital y la cual puedes encender en luz naranja pars una mejor visibilidad con poca luz. En cuestion de alimentacion lo puedes hacer con un eliminador de 9 volts o con pilas AAA , NO VIENE CON ELIMINADOR SOLO TRAE BATERIAS. Yo lo uso con baterias recargables y funciona bien. Lo unico pari mi que no me gusto fue el boton de encendido el cual es de plastico pero se ve muy sencillo y no se sinte de muy buen calidad. POR ULTIMO YO SIN DUDAR RECOMIENDO QUE LO COMPREN CREO QUE VALE LA PENA. ESTOY MUY AGUSTO CON EL AFINADOR
