Korg CA-40 Chromatic Handheld Tuner

Gearank High Notes

Gearank Recommendation

The CA-40 appeared on our recommended list for Handheld Tuners from our first edition in March 2017 until it had to be removed due to a lack of availability in December 2019.

Overview

The Korg CA-40 has a handy battery saving feature where it turns itself off when left on unused for 20 minutes.

It's not specifically designed for guitar but has found a place with guitarists who also play other instruments from ukulele to brass and woodwind, or who share it with others at home who play those instruments.

Although it does have a bypass output jack which Korg say is good for live use, like all handheld tuners it's not particularly practical for guitarists to use during a live performance setting but is fine for tuning in between sets, home use and practice sessions.
