Korg CA-30 Chromatic Tuner Review
The Korg CA-30 is a chromatic tuner for guitar, bass, and other instruments. Since it is chromatic (not confined to any one scale or set of notes), it is especially good for ukuleles, violins, mandolins, or any other instrument outside the traditional E-A-D-G-B-E monotony.
It features a built-in microphone for acoustic guitar, along with the obligatory input jack for electric instruments. The large LCD screen displays a precise, not-too-jittery needle for accurate sharp and flat adjustments, aided by three LEDs above the screen. The left red LED means you’re too flat, the right says you’re too sharp, and the green one in the middle says you’re right on the money.
Tuning can be changed to different Hz variations for musical non-conformants and the unit has a detection range of C1, freakishly low, to C8, crazily high. Those are scientific terms, I think.
The Korg CA-30 Chromatic Tuner is a solid investment and depending on where you get it from, prices range from the low teens to almost 20.
