Description
Introducing the TC Electronic PolyTune 3, a pedal tuner that takes instrument tuning to a whole new level. This compact, intuitive, and reliable tuner boasts an impressive accuracy within 0.02 cents, making it an essential addition to your music gear. The PolyTune 3 simplifies your tuning process by allowing you to strum all strings simultaneously to identify the out-of-tune ones at a glance, or tune up one string at a time.
Designed with musicians in mind, the built-in BonaFide Buffer circuitry enhances your tone for long cable runs, providing a treble and transient response that is closer to plugging directly into an amp. This innovative feature is switchable to true bypass, giving you control over your signal path.
Enhance your creativity with the PolyTune 3's alternate tuning modes, allowing for fast and easy exploration of new tunings even in the middle of a set. Plus, the improved auto-dimming LED display makes tuning comfortable in any environment, indoors or out.
