Wide Range of Pitch Detection
This compact chromatic tuner supports a broad range of C1 (32.70 Hz)-C8 (4186.01 Hz), allowing speedy and high-precision tuning of wind, string, keyboard, and other instruments. This tuner is ideal for tuning even low-register notes containing numerous overtones that are often difficult to tune. A high-sensitivity mic is built-in, allowing easy and accurate tuning of acoustic instruments such as ukuleles. A separately sold CM-100 contact mic can also be used to send the vibrations directly to the tuner for even more accurate tuning.

Ultra-compact body with a "Tilt Slit"
Although the CA-1 is small, thin, and light, don’t let its pocket-sized body fool you. The CA-1 packs the functionality needed for tuning a wide range of instruments. 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
In addition to visual tuning via meter, the CA-1 can play reference pitches from its internal speaker (Sound Out) for tuning by ear. Each press of the Sound switch will cycle through the A4-Bb4 notes commonly used for tuning wind instruments. Or you can hold down the Sound switch to change the cycle to the semitone intervals from C4 through C5 (one octave), allowing reference pitches for any instrument to be sounded quickly.

Adjustable Calibration
The Calibration function (410-480 Hz) supports a wide range of standard pitches, and can be adjusted in 1 Hz steps for accurate and flexible tuning to any song or key. Thanks to the Memory Backup function, the Calibration and reference pitch are remembered even when the power is turned off.
(However, these settings will be initialized when the batteries are replaced.)

Auto Power Off Function
The power will turn off automatically, if the unit is left powered-on for 20 minutes without performing any operation, 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.

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). * 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.

A new chromatic pedal tuner with extreme precision and advanced functionality for the pro guitarists and bassist

The pitchblack+ is a high-end pro-quality pedal tuner boasting ultra-high tuning accuracy within a range of +/-0.1 cents. Housed in a sleek black aluminum die cast body it packs a versatile range of tuning modes such as chromatic, standard (guitar/bass), open D, open E, open G, open A, and DADGAD, and also lets you create up to five custom tuning programs of your own with any temperament you specify. This is ideal for accommodating special tunings such as ethnic instruments and stretched tuning. The pitchblack+ also supports tuning for seven-string guitars and six-string basses. In addition, you can also use the flat tuning mode to tune your instrument as many as seven semitones below standard pitch. With a broad tuning range of E0 (20.60 Hz) to C8 (4186 Hz) and calibration that's adjustable in a range of 436--445 Hz, you'll be able to tune with an unprecedented degree of accuracy. The pitchblack+ offers a new level of high-precision tuning demanded by professional guitar and bass players for the recording studio or in live performance.

The pitchblack+ features a large 13-segment LED meter. In conjunction with the tuning guides located below the meter that indicates whether your instrument is sharp or flat, the smooth-moving LEDs provide highly visible confirmation for accurate tuning at any viewing angle. The note name, tuning mode, and calibration are shown by large, highly-readable displays in green and red, and the tuner on/off status is shown by a red LED, ensuring that you'll see everything you need even if you're on a dimly-lit stage. You can choose between two types of display modes: Single mode or Double mode. In Single mode, you can choose between Meter mode, Full Strobe mode, Half Strobe mode, or Mirror mode. In Double mode, you can choose from two newly developed modes; Focus mode 1 and Focus mode 2 which offer even greater precision with excellent visibility.

Dual input jacks allow two instruments to be connected. True Bypass ensures that the input signal is unaffected.

As a professional pedal tuner, the pitchblack+ provides A and B input jacks to which you can connect two different guitars or basses, and individually specify a separate calibration, tuning mode, flat tuning, and display mode for each guitar/bass (input). If only a single instrument is connected, you can specify two different tuning settings and switch between them by pressing the "INPUT SELECT" foot switch. This supports situations such as when you're playing more than one guitar/bass in a live situation, or sophisticated musical needs such as using different tunings with a single guitar for multiple songs. The sound is muted when tuning is active, and when tuner is off the True Bypass feature ensures that the input signal from your instrument is not colored in any way whatsoever. With functionality such as this, the pitchblack+ can provide high-precision tuning capability while being integrated into your guitar or bass pedalboard and amp setup.

Fits into your pedalboard, and DC output powers other pedals

The Pitchblack+ works great with your current pedalboard system. It provides a DC OUT jack that can supply power to other effect pedals when the optional AC adaptor is used. By connecting the included DC cable, you can supply up to 200 mA of power to multiple effect pedals that require a 9V supply, simplifying the power connections in your effect board.
