KORG GA-CS

Korg GA Custom
Chromatic Tuner for Guitar/Bass
Card-type compact tuners have long-been KORG’s most popular tuners. The diverse lineup includes the GA series for guitar/bass and the multi-use CA series, and has continued to support the tuning needs of beginners and professionals alike. We now introduce a new model: the GA Custom.
The GA Custom features a large 3D visual meter, the first of its kind for a compact tuner. Three-dimensional lights and versatile display modes deliver an unprecedented level of visibility. Its ultra-high ± cent tuning precision also meets professional needs. The flat body with rubberized exterior is even more compact and portable than ever. A high-sensitivity mic is built-in, allowing it to be used not only with guitar/bass but also with orchestral and acoustic instruments. The GA Custom is a new type of compact tuner that packs a ton of high-end functionality into a convenient and highly portable package.
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. In addition to the standard black, this tuner is available as a limited edition of color variations. Choose vivid red, bright blue, or sophisticated white.
Korg is resolved to continue to create innovative and uncompromising instruments and accessories which maintain the high quality that inspires professional artists and creators, and yet are approachable enough for anyone to play. The musical instruments Korg will deliver are reflections of the ideas and values of the many artists and users who continue to love Korg products - now and into the future.

I find this particular Korg bass and guitar tuner to suit my needs just fine. Korg has done an awesome job with the 3D display on this unit. The size of this tuner is small at 3 5/8" long x 2 1/2" wide and 5/8" thick. It will fit in a front shirt pocket just fine. This tuner is very easy to use and understand. The back side has a rubber feel along with three very small thin rubber feet. I checked the accuracy of this tuner against two other name brand tuners that I have and it appears to be very sensitive and renders amazing results. It has three display modes and you can change the pitch calibration if so desired. If you are looking for a permanent "in-line" tuner, I would NOT buy this Korg for that purpose. Also, it uses 2 AAA batteries for power and does NOT use 120v AC to DC conversion. I see a lot of people bitching and whining about this and that concerning this tuner but just KNOW what you are getting. For me, the portability and easy to read display are worth it. This tuner can be used as a chromatic type OR you can plug in your instrument with a 1/4" TRS "MONO" cable. Good job on this one !! 5 stars for sure :)
