What we say:

Meet the big brother to the ever popular Korg CA-1 Chromatic Tuner. There's a reason why the CA-1 is one of the highest selling tuners on the market and Korg have listened to customers feedback and make a couple of tweaks to make its follow up, the CA-2 even more practical and efficient. Boasting an even longer battery life than its predecessor, there's no chance of this running out when its needed. It also features a clearer display screen so that tuning up has never been easier! With high accuracy tuning capabilities that can be used to suit a number of instruments, the CA-1 is compact, lightweight and extremely portable. While many tuners around this price range simply do the basics, the CA-1 allows the user to tune to more advanced keys with marks for major thirds and minor thirds. It also offers the useful option of a reference tone, giving a handy guideline while you tune up. Overall, the Korg CA-2 Chromatic is a reasonably priced and really handy little piece of equipment to have in your pocket that doesn't break the bank.


Having become a popular standard in tuners and an indispensable item for brass band or orchestra thanks to its superior basic functionality and convenient functions, the CA series now has a fresh new look. Carrying on the stylish design with its simple layout of the basic functions, the note name display has been enlarged and the meter made even more visible. This is a must-have item not only for beginners but also for a wide range of musical instrument performers. The CA-2 delivers the high precision, sensitivity, and simple ease of use that you expect from KORG tuners, providing stable tuning functionality in any situation from personal practice to ensembles and concert practice.
