GA30

An easy-to-use dedicated guitar/bass tuner
This dedicated guitar/bass tuner lets you select either Guitar mode or Bass mode for truly easy operation with automatically detected pitch. The wide detection range supports 7-string guitar (7B through 1E) in Guitar mode, and 6-string bass (Low-B, Hi-C) in Bass mode. A high-sensitivity mic is built-in, allowing easy and accurate tuning of acoustic guitars.

Highly portable and ultra-compact body with a "tilt slit"
Although the GA-30 is small, thin, and light, don’t let its pocket-sized body fool you. The GA-30 can accurately tune any guitar or bass. From studio to stage, tuning is easy and convenient. The back of the unit includes a unique arc-shaped "tilt slit" that lets you insert a plastic card for use as a handy stand.

High-precision LCD meter indicates the detected pitch
The meter section uses a LCD needle, combining the accuracy of an LCD with the easy visibility of a needle, and providing a stable display. Additional visual feedback is provided by LEDs that indicate pitch deviation.

Internal speaker provides a reference pitch (Sound Out)
In addition to visual tuning via meter, the GA-30 can play reference pitches from its internal speaker (Sound Out) for tuning by ear. Each press of the Sound switch will cycle the output sound through 7B->6E->5A->4D->3G->2B->1E in Guitar mode, or LB->4E->3A->2D->1G->HC in Bass mode.

Quinta Flat Tuning mode -- a world-wide first!
The GA-30ﾕs Quinta Flat Tuning mode supports the lowered tunings used in heavy metal styles to give more weight to the sound. Until now, dedicated guitar tuners have supported a maximum of only four semitones below standard pitch, but the GA-30 gives you five steps of flatted tuning, extending as far as five semitones below standard pitch, and supporting even super-long scale guitars that are five frets longer than conventional guitars.

Auto Power Off function
If you leave the unit powered-on for 20 minutes without performing any operation, the Auto Power Off function will turn the power off automatically, avoiding unnecessary battery consumption.

Approximately 100 hours of continuous use
Low-power consumption design allows an amazing 100 hours (approximate) of continuous battery life (A4 continuous input, Meter mode, zinc-carbon batteries).

* Even if the pitch is within the detection range, detection may not be possible for instrumental sounds that contain a large number of overtones or have a rapid decay.
