Review: for Guitar, Bass, Violin, Ukulele and my Yamaha Guitalele too - This is amazing piece of kit, light and small. Very well made, easy to use, 4 different modes, will work for Guitar, Bass, Violin, Ukulele key c/d and my new love Yamaha Guitalele too (for the guitalele - start from A,D,G,B,E,A). I was choosing between the mono-colour one Tiger Chromatic Guitar Tuner and this colour one, I'm glad that I picked this, looks bright and smart. Can see very well with the dimmed light. Although its not from desertcart, but delivery was fast too! Review: Great little tuner - Very nice little tuner. Sits well on the head. The screen can be pointed in any angle. The screen is very clear and precise. It speeds up tuning so much if you are used to using a normal mic/plug in tuner sitting on your knee whilst tuning! Very easy to tune to non standard tunings as well thanks to the chromatic setting which will tune to any note (it has a guitar setting that locks in on the standard tuning) Overall very good product ## Features - Chromatic clip-on guitar tuner - The guitar tuner offers a tuning scale to suit a wide range of instruments including guitar, bass, violin and ukulele - Auto-off function to extend the battery life - Measures 35mm length by 40mm width by 52mm height - Heavy duty design ## Technical Specifications | Specification | Value | |---------------|-------| | Product Dimensions | 2.7 x 3.7 x 5 cm; 30 g | | Batteries | 1 Product Specific batteries required. | | Item model number | GTU2-BK | | Body Material | Lithium | | Colour | black | | Country Produced In | china | | Item Weight | 30 g | ## Images ![Theodore GTU2-BK Chromatic Clip-on Guitar Tuner, Black - Image 1](https://m.media-amazon.com/images/I/61bjaeMi4mL.jpg) ![Theodore GTU2-BK Chromatic Clip-on Guitar Tuner, Black - Image 2](https://m.media-amazon.com/images/I/61LH5cXNWVL.jpg) ![Theodore GTU2-BK Chromatic Clip-on Guitar Tuner, Black - Image 3](https://m.media-amazon.com/images/I/61727f6wJFL.jpg) ![Theodore GTU2-BK Chromatic Clip-on Guitar Tuner, Black - Image 4](https://m.media-amazon.com/images/I/61kvGIOiHiL.jpg) ![Theodore GTU2-BK Chromatic Clip-on Guitar Tuner, Black - Image 5](https://m.media-amazon.com/images/I/71UQ8IcEWyL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ for Guitar, Bass, Violin, Ukulele and my Yamaha Guitalele too *by E***A on 14 October 2012* This is amazing piece of kit, light and small.

The screen can be pointed in any angle. The screen is very clear and precise. It speeds up tuning so much if you are used to using a normal mic/plug in tuner sitting on your knee whilst tuning! Very easy to tune to non standard tunings as well thanks to the chromatic setting which will tune to any note (it has a guitar setting that locks in on the standard tuning) Overall very good product ### ⭐⭐⭐⭐⭐ A versitile little item. *by C***E on 22 December 2013* Only been using it for a day but have tuned an electric guitar and elect4ro acoustic and Ukelele with great ease. I did not need it for the first two but did it after tuning it with an expensive tuner that I know is accurate and this little item is as good as it gets. Easy to read and the ability to set it to different instruments is also good which is why I bought it for the Ukelele and my grandson to tune it also tunes a violin. I like it. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/65394177-theodore-gtu2-bk-chromatic-clip-on-guitar-tuner-black](https://www.desertcart.jp/products/65394177-theodore-gtu2-bk-chromatic-clip-on-guitar-tuner-black) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-31*
