In 2015 Korg launched their new Custom Shop. This is a label that they only give to their top tier tuners that perform above the rest. This GA Custom tuner is one of the few tuners to get this badge thanks to its small footprint, massive screen and best in class accuracy.
While most tuners in this small card style will have accuracy of around +/- 1 cent the GA Custom takes it to another level. With +/-0.1 cent accuracy you can get closer to perfect pitch than ever before making your mix sound even better.
Stunning New Display
Korg have come up with a brand new type of tuning display that is brighter, easier to read and more accurate that their other tuners. Using bright blue LEDs in a unique pattern you can easily determine when you guitar is on tune even under stage lights.
Guitar, Bass and More
While this tuner does have your normal 1/4" in for your electric guitar and bass needs. It also has a high quality microphone built in which is perfect for brass, woodwind and acoustic string instruments when an emergency adjustment is needed.
Small Yet Strong
Somehow even with all of these major updates Korg have managed to slim down the GA some more. They have also given it a much tougher rubberized exterior that means you can carry this is your gigbag from gig to gig knowing that nothing will go wrong with this little piece of kit.
Here's what Korg say about the GA Custom Tuner
"Custom Shop," the mark of ultimate quality
KORG tuners have a 40-year history that began with the world's first needle-style tuner. While we have produced many different types of tuners, including tuners with unrivaled precision and tuners with epoch-making functionality, these products were made possible by KORG's unwavering commitment to quality. In other words, our attitude of sincerely listening to the voice of the user, our revolutionary ideas, and our high level of technological ability are what underlie the long history of KORG tuners.
Now, KORG announces a new lineup aimed at achieving even greater accomplishments. The name "Custom Shop" designates this tuner as a flagship model that is representative of KORG's highest levels of technology. Its design features a beautiful meter displayed by a CMD panel, ultra-precision detection, and careful attention paid to appearance and feel. KORG's high technological ability and commitment to quality have taken shape as the "Custom Shop" name.
3D visual meter creates a revolutionary visual effect
The 3D visual meter exemplifies the Custom Shop series. A large and easily visible note name indication and the distinct movement of brightly illuminated LEDs make the pitch difference and change instantly recognizable. This new 3D visual meter makes it simple to tune with a precision of +/-0.1 cent.
Ultra-high tuning accuracy of +/- 0.1 cents
Designed with the professional user in mind, KORG's GA Custom offers extremely accurate tuning with a detection range of +/- 0.1 cents, a level of precision that is uncommon of compact tuners. With the GA Custom, players of all styles can now enjoy the same ultra-high precision offered in KORG's flagship tuner, the Pitchblack Pro.
Three meter display modes
Three types of display modes are offered: Regular, Strobe, and Half Strobe. Each mode can be easily selected according to the user's preference. Strobe and Half Strobe mode reflect the extreme precision of the GA Custom, making it more convenient to tune accurately.
Compact flat design
The meter display area has been made larger and easier to see, while the body has been made even more compact. The flat design is excellent for both visibility and portability. With a rubberized exterior, the body is also easy to hold. There's a tilt stand on the rear, allowing you insert a pick to make the unit stand on its own.
