Description

Edit description

The TC Electronic PolyTune Mini 3 black is a compact but mighty pedal tuner that’s designed for musicians who demand both precision and practicality. Despite its small size, this pedal doesn't skimp on features, making it a must-have for any guitarist's pedalboard. Equipped with the BonaFide Buffer, the PolyTune Mini 3 ensures your tone remains vibrant and clear, no matter how long your cable runs. This buffer can be switched off to revert to true bypass mode, giving you control over your signal path.

The standout feature of this tuner is its polyphonic tuning capability, which allows you to strum all strings and instantly see which ones need adjusting. This is a time-saver on stage, letting you tune up quickly without pausing the show. For those who prefer traditional methods, it seamlessly switches to a monophonic mode for detailed tuning.

Visibility is key during performances, and with 109 bright LEDs, the PolyTune Mini 3's display is easy to read whether you're under stage lights or in daylight. The tuner also features an Always-On mode, enabling continuous tuning checks without interrupting your performance, ensuring that you're always in tune.

This pedal is not only about keeping you in tune, but also about enhancing your creative exploration. With alternate tuning modes, you can experiment with open and slide tunings on the fly, adding new dimensions to your music.

Built-in BonaFide Buffer to maintain tone integrity
Polyphonic tuning for all strings at once
Monophonic mode for single-string tuning
Always-On mode for continuous tuning checks
