Review: This is a great tuner to use - This is a great tuner to use, very readable from a distance. The tuner supports a range of different tunings, although I only use A440. There are three tunin modes - standard, semi-strobe and strobe. The standard tuning mode is quick and accurate for day-to-day use and strobe mode is very useful for guitar setup, setting intonation etc very accurately. The lock-on for the chromatic tuning seems reliable and it doesn't jump around like some cheaper tuners that can be inconsistent measuring the pitch of a note, especially lower notes on the Bass. Accuracy is stated to be 0.2 cents, which almost as good as the stupidly expensive peterson strobe tuners. My only slight niggles are that there isn't an external power option and a full bypass so that the tuner can be left in-circuit. It isnt a problem with my Eden bass amp as it has a seperate tuner output, but may one to bear in mind. Overall it is quite good value, and a great product. It does the same thing as cheaper tuners, but is accurate, is easy to use and the display has great visbility, unlike the cheaper LCD display Korg tuners Review: Accurate and easy to read display. - Excellent tuner, stylish, clear display and very accurate very good value for money. ## Features - The KORG GA Custom features a large 3D visual meter, the first of its kind for a compact tuner - The GA Custom is a compact tuner that packs a ton of high-end functionality into a convenient and highly portable package - High-sensitivity mic is built-in, allowing use with acoustic & orchestral instruments - Ultra-high tuning accuracy of +/- 0.1 cents - Three meter display modes ## Technical Specifications | Specification | Value | |---------------|-------| | Product Dimensions | 15.24 x 2.54 x 10.16 cm; 113.4 g | | Batteries | 2 AAA batteries required.

I really like the GA; the display is great to look at but more importantly it's very clear and easy to use. In Regular mode, it's extremely quick to tune my guitars. The manual isn't clear, but I think the Regular mode is accurate to +/- 1 cent. The Strobe mode is much more accurate at +/- 0.1 cent, for times when that is needed, for example when recording or setting intonation. I don't use the third mode, half-strobe, much, as the Regular and Strobe modes give me all that I want (the manual doesn't explain why you might want to use the half-strobe mode, other than as a visual variation). This style of tuner is also available as a pedal (Pitchblack Custom), clip-on (Sledgehammer Pro) and rack (Pitchblack Pro), although the rack version is only accurate to +/- 1 cent. Overall, I'm extremely happy with this tuner and would recommend it. The only caveat is that it's made of plastic and it doesn't feel too robust, so it's probably not something for stage use, where the pedal or rack would be much better. ## Frequently Bought Together - Korg - GA-CS Pitchblack Custom Pocket Tuner with 3D Display - Black - D'Addario String Height Gauge - GHS Fast Fret Guitar String Cleaner and Lubricant --- ## 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.co.za/products/53893979-korg-ga-cs-pitchblack-custom-pocket-tuner-with-3d-display](https://www.desertcart.co.za/products/53893979-korg-ga-cs-pitchblack-custom-pocket-tuner-with-3d-display) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-30*
