It features a dual-display, an easy-to-see needle-type indicator and a backlit LCD screen that shows the battery level, sound output level, calibration, key and note name. Additional design features include a large dial that makes it easy to select the desired mode, finger-friendly buttons and a rear-mounted stand that lets the unit stand by itself. A sophisticated silver aluminum panel contributes to its sleek, new look. OT-120 uses a high-precision needle-type meter to accurately indicate any pitch discrepancy. The speed at which the needle responds to the input can be changed over a range of three steps; you can choose rapid or slow needle movement to match your tuning preference. Box Contains 1x Chromatic Orchestral Tuner Review: Includes Pythagorean mode - really useful for early musicians - 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. Review: Handy and brilliant - Does exactly what it says. Excellent bit of kit, easy to use. Tuning temperament feature was my reason for purchase. First rate. ## Features - Tune wind and string instruments in a flash with the KORG OT-120, - Dual display provides both a needle-type meter and an LCD for excellent visibility. - backlit LCD screen that shows the battery level, sound output level, calibration, key and note name. - Both auto and manual tuning modes are provided - Use with the optional KORG CM300 Contact Mic for accurate tuning in noisy environments ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000GFCYPS | | Best Sellers Rank | 14,945 in Musical Instruments & DJ ( See Top 100 in Musical Instruments & DJ ) 237 in Tuners | | Body Material | Aluminum | | Brand | KORG | | Brand Name | KORG | | Colour | Black | | Connector Type | USB | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 1,113 Reviews | | Finish Type | Varnished or varnished | | Global Trade Identification Number | 04959112043985 | | Included Components | Velour soft case | | Item Dimensions | 13.9 x 9.7 x 5.9 centimetres | | Item Type Name | Korg OT-120 Orchestral Tuner | | Item Weight | 193 Grams | | Item dimensions L x W x H | 13.9 x 9.7 x 5.9 centimetres | | Item weight | 193 Grams | | Manufacturer | KORG | | Material | Aluminum | | Model Name | OT120 | | Model Number | OT120 | | Model name | OT120 | | Part Number | TUOT120 | | Set Name | False | | Unit Count | 1 Count | ## Product Details - **Brand:** KORG - **Colour:** Black - **Item dimensions L x W x H:** 13.9 x 9.7 x 5.9 centimetres - **Material:** Aluminum - **Model name:** OT120 ## Images ![Korg - OT12O Pocket Chromatic Orchestral Tuner - Image 1](https://m.media-amazon.com/images/I/71Y075om7XL.jpg) ## Questions & Answers **Q: Has anyone had any success with using this device to tune a piano?** A: Anyone who says or thinks that they can tune a piano with this device has a) never tuned a piano before. b) doesn't have a trained ear that will allow them to hear that the end result is severely mediocre at best. c) doesn't understand that it took a piano tuner at least 500 tunings before they were confident enough to even call themselves one. There's nothing wrong with trying to tune your own piano. But to think that this device is going to "get you there" is a misconception. The fact that this is being sold as a piano tuning device is false advertising. Go visit any piano technician in your area and I guarantee they will laugh at the notion that this device will accurately tune a piano. You want the real deal? Download TuneLab for free. It's a $350 app and you can use the full program for free with the exception that it will time out for 2 minutes every 14 notes. Remember. 95% of people can't hear a piano that's out of tune. When they notice it n it's WAY out of tune. So, pay no attention to positive reviews that say this worked. I guarantee you, it didn't. But, to each their own. Just know that there are far better ways to learn. **Q: Could this tune down to 432 instead of 440?** A: Hi, Regina! I just tried it out on the tuner, and it does indeed tune down to 432! I didn't see just how far down it will go - guessing you're a Baroque player? If you would like me to check how far down it will tune (415 or 392), let me know. This is a great little tuner, and does all my old one did and more - for about 1/3 the cost!! **Q: Does it offer a just intonation setting under the additional temperament presets?** A: I'm on the road at the moment without it but I'm sure that no, it doesn't. It has a fair number of temperaments available, while unfortunately 1/4 comma meantone is not one of them. Only 1/6 comma E- or D#. I seem to be playing more and more in 1/4 comma so that's a bit of a downer. I'm not even sure that Just Intonation is a temperament, as the pure intervals move with the chords being played through all keys in just. I wouldn't be surprised if there is a tuner that can do it, maybe an iPhone app, but I think the only way the Korg would be able to do it is to use the temperament closest to pure for the notes you want to check and then know how much to add or subtract when you are reading the meter.Good question though. It makes me think.... It's been a great tuner for me other than the 1/4 comma problem, where I've had to set the frets with a ruler and then make small adjustments to whatever keyboard instrument is there. It's survived several drops from the music stand and the batteries seem to last forever. **Q: there are 8 different temperaments listed on this tuner - but not equal temperament - which temperament is used for tuning the piano** A: The Transpose/Temperament button allows you to transpose the pitch up or down, or use a particular temperament and all the listed temperaments are not equal temperament. If you cycle through the Transpose/Temperament button until the screen is blank, i.e. IT does not list either a specific temperament or a pitch (C#, D, D# etc.), then that is equal temperament that you would use for tuning the piano. The calibration should read A - 440. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Includes Pythagorean mode - really useful for early musicians *by G***F on 6 April 2022* I make and play ancient and Medieval musical instruments.

Excellent bit of kit, easy to use. Tuning temperament feature was my reason for purchase. First rate. ### ⭐⭐⭐⭐ Good Tuner *by M***B on 11 June 2020* 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. ## Frequently Bought Together - Korg OT-120 Orchestral Tuner - Korg CM100L Clip-On Contact microphone For Tuners - CONCHACIELO Professional Piano Tuning Kit: Universal Piano Tuning Tools Kit Set with Portable Case,Tuning Wrench, Wrench Fastener, Tuning Mute. for Tuning Beginner, Professional Tuner (Pro Set) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/49635193-korg-ot12o-pocket-chromatic-orchestral-tuner](https://www.desertcart.tn/products/49635193-korg-ot12o-pocket-chromatic-orchestral-tuner) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-07*
