CT-20 Tuner

D'Addario, the string and accessories giant, expanded into pedal tuners with the CT-20, bringing their precision engineering to pedalboard essentials. The CT-20 offers professional-grade tuning accuracy in a slim, space-efficient format.

The 32-bit processor delivers fast note detection with accuracy to 0.05 cents, making it suitable for precise intonation work. The full-color vertical LED display provides excellent visibility in any lighting condition with red, yellow, and green segments clearly indicating tuning status.

Housed in a rugged aluminum enclosure, the CT-20 features true bypass switching to preserve your tone when not in use. The slender profile fits where most pedals cannot, maximizing pedalboard real estate. It runs on 9V DC power or the included 9V battery.
