New feature-packed models join the best-selling GA series of compact tuners. With superior features like a large, easy-to-see, LCD needle-style display, the GA-40 Guitar/Bass Tuner is a great value!

Dedicated guitar and bass tuner with large LCD for easy viewing

The GA-40 is a dedicated, easy-to-operate guitar/bass tuner with automatic pitch detection. In Guitar mode it supports seven-string guitars (7B through 1E), and in Bass mode it supports six-string basses (Low-B and Hi-C). With the precision you expect from KORG, the GA-40 indicates the pitch quickly and accurately. The LCD needle-style display provides both the accuracy of an LCD as well as the easy viewing of a needle indicator, and the display has been enlarged for even better visibility. You can also use the built-in high-sensitivity microphone to tune an acoustic guitar.

Sound Out function produces a reference tone from the internal speaker

In addition to letting you tune visually using the meter, the GA-40 provides a Sound Out function that plays a reference tone through the internal speaker, letting you tune by ear. Each time you press the Sound switch, the tone will cycle through 7B→6E→5A→4D→3G→2B→1E in Guitar mode, or through LB→4E→3A→2D→1G→HC in Bass mode.

Quinta Flat Tuning mode

To support the dropped tunings used in heavy metal styles to produce a powerfully massive sound, the GA-40 provides a Quinta Flat Tuning mode that lets you detect dropped tunings of one through five semitones. This lets you tune super-long scale guitars that extend below the pitch range of conventional guitars.
