Description

Edit description

Unleash your guitar's potential with the Harley Benton CPT-20, a sleek and reliable pedal tuner designed for both guitarists and bassists. This chromatic floor tuner is engineered to ensure that your instrument always hits the right note, whether you're on stage or in the studio. Its LED/LCD Display provides a clear and precise tuning interface, allowing for quick adjustments even in low-light settings. With a tuning range from A (27.5 Hz) to C (4168 Hz), it accommodates a wide variety of musical styles and preferences.

The CPT-20 offers the convenience of True Bypass, ensuring that your tone remains uncolored when the pedal is not in use. Musicians will appreciate the tuner's accuracy, which is rated at an impressive ±1%. Compact and lightweight, this pedal easily integrates into any setup without adding unnecessary bulk.
