For nearly a decade, the Korg GA-30 Guitar and Bass Tuner has stood among the top-selling tuners on the planet. Now meet the GA-1, offering the same excellent features with a new, enhanced design – all at the same great price!

Ultra-compact LCD Needle-Style Dedicated Guitar and Bass Tuner
High accuracy and superb functionality have made Korg tuners the worldwide favorite. And now, the new GA-1 joins the best-selling GA series of tuners. With even more features, like a pitch reference tone and quinta-flat tuning, the GA-1 tuner packs basic functionality and convenient tuning functions into ultra-compact bodies.

Features:
• Ultra-compact design.
• High-precision LCD needle-type meter for stable tuning.
• Quinta Flat Tuning mode lets you tune 1--5 semitones flat
• Supports 7-string guitar tunings.
• Sound Out can produce a reference tone from the internal speaker.
• Auto Power Off function conserves battery life.
• Approximately 100 hours of continuous use.


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, donʼt 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
The GA-1ʼs Quinta Flat Tuning mode supports the lowered tunings used in heavy metal styles to give more weight to the sound. Most dedicated guitar tuners support 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).


* 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.

Korg tuners and metronomes purchased from a Korg UK authorized dealer now have a three year warranty.

    Main features

  • A compact and unique high-performance chromatic tuner.

  • Bright LEDs are used to display three types of tuning modes.

  • A wide detection range of A0--C8 (88 notes).

  • Calibration range of 410Hz-480Hz can be adjusted to support various concert pitches.

  • Built-in condenser mic lets you tune acoustic instruments.

  • Designed for low power consumption.


  • Tuning comes full circle
    The DT-4 is a unique style of chromatic tuner in which LEDs around its circumference indicate how close the input pitch is to the note name displayed in the center. In spite of its compact size (fits in the palm of your hand), the illuminated circumference and large note name display provide excellent visibility, allowing high-precision tuning over a range of A0 (27.50 Hz)--C8 (4186.01 Hz). The adjustable calibration lets you specify the reference pitch in a range of 410 Hz--480 Hz (1 Hz steps). Its design emphasizes comfort and ease of use, with function-selecting switches placed for quick and easy access.

    Three new tuning modes
    The DT-4 illuminates the green LEDs around its circumference in one of three tuning modes: Strobe, Mirror, or Meter. There are also triangular red tuning guides that indicate whether the input is sharp or flat, helping you tune your instrument more precisely.

    Strobe mode
    The green LEDs will stop moving when your instrument is in tune. The LEDs will move in a clockwise direction if the pitch of your instrument is sharp, or counter-clockwise if it is flat. When the tuning is correct, the two tuning guides will also light simultaneously.

    Mirror mode
    Mirror mode is a new concept of tuning found only in the DT-4. When the two green LED�s at the lower left and right coincide, you're perfectly tuned. The bright green LED will move to the right of center if the input pitch is sharp, or to the left if it is flat. The distance between the bright green and dim green LED�s indicate the distance to perfect tuning.

    Meter mode
    Tune your instrument so that the bright green LED is aligned with the red tuning guide in the center as on a conventional needle type tuner.

    Designed for easy operation and low power consumption
    The DT-4 is designed for easy operation, with switches located for effortless operation when held in the palm of your hand.

    In Strobe mode if approximately thirty seconds have elapsed without any input sound, the rotating red LED�s will go dark. If approximately ten minutes have elapsed with no audio input while powered-on, the DT-4 will automatically turn off to prevent unnecessary battery consumption.
