An Easy-to-Use Dedicated Guitar and 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.

Ultra-compact Body with a "Tilt Slit"
Although the GA-1 is small, thin, and light, don’t let its pocket-sized body fool you. The GA-1 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
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.

Sound Out -- Internal Speaker Provides a Reference Pitch
In addition to visual tuning via meter, the GA-1 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-1’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-1 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).

Ideal Positioning for Easier, More Accurate Use

This will work well with acoustic guitars and basses that will not tune easily. The CM-100 Contact Microphone is a perfect compliment to any tuner that offers an audio input jack. The mic can be positioned to get a more sensitive reading, while allowing the tuner to be positioned for easier reading. Simply place the mic on your instrument and plug into the tuner.. and start tuning.

The jack is a 1/4" male phone connector.

Metronome Stand for GA1
This stand will keep your tuner off your music stand and prevent it from falling.
