Korg CA-1 Chromatic Tuner

The Korg CA-1 Chromatic Tuner is an ultra-compact and highly accurate tuner designed for musicians who require dependable tuning performance in a portable format. Ideal for brass bands, orchestras, string players, keyboardists, guitarists, bassists, and other instrumentalists, the CA-1 combines precise pitch detection, intuitive operation, and long battery life in a lightweight design.

As part of Korg's renowned CA series, the CA-1 delivers professional tuning functionality while remaining simple enough for beginners and students. Its versatile features make it an excellent companion for practice sessions, rehearsals, lessons, and live performances.

Wide Chromatic Detection Range

The CA-1 offers an extensive pitch detection range from A0 (27.50 Hz) to C8 (4186.01 Hz), enabling accurate tuning across a broad spectrum of instruments. The wide range makes it suitable for low-register instruments, high-pitched orchestral instruments, and everything in between.

Its sensitive detection system accurately responds to complex instrument overtones, providing reliable tuning performance for various acoustic and electronic instruments.

High-Precision LCD Needle Meter

The tuner features a highly visible LCD needle-style meter that combines the familiarity of an analog needle display with the precision of digital technology. LED indicators provide additional visual feedback, making it easy to identify whether notes are sharp, flat, or perfectly in tune.

The stable display allows musicians to tune quickly and accurately, even in rehearsal and performance environments.

Reference Tone with Sound Out Function

In addition to visual tuning, the CA-1 includes a Sound Out function that generates reference pitches through its built-in speaker. This allows musicians to tune by ear and develop better pitch recognition skills.

The reference tone function supports notes from C4 to C5 and provides an additional tuning method for instrumental practice and ear training.

Adjustable Calibration

The calibration function supports concert pitches from A4 = 410 Hz to 480 Hz in precise 1 Hz increments. This flexibility makes the tuner suitable for various musical situations, including orchestral ensembles and performances that require alternative tuning standards.

The built-in memory backup automatically retains calibration settings and reference pitch information even after powering off.

Pure Major and Minor Third Indicators

The meter includes dedicated markings for pure major thirds and minor thirds. These indicators help ensemble musicians achieve more accurate harmonic relationships when performing in groups, resulting in smoother and more balanced intonation.

This feature is particularly valuable for brass bands, orchestras, and chamber ensembles where harmonic tuning accuracy is essential.

Ultra-Compact Portable Design

The CA-1 features a slim and lightweight design that fits comfortably into instrument cases, gig bags, or pockets. Despite its compact dimensions, it provides a large and easy-to-read display that remains practical during everyday use.

The rear panel includes Korg's unique Tilt Slit design, allowing the tuner to be positioned at an angle for improved visibility during practice and performance.

Exceptional Battery Life

Thanks to its low-power design, the CA-1 delivers approximately 100 hours of continuous operation on just two AAA batteries. An Auto Power Off function automatically turns the unit off after periods of inactivity, helping maximize battery life.
