In this review post, we’re going to be discussing the TC Electronic PolyTune 3 Polyphonic LED Guitar Tuner Pedal w/ Buffer, including an overview of its unique features.

Product Description

When it was introduced in 2010, the original POLYTUNE forever revolutionized the way musicians tune their instruments. Praised by professional and amateur players, guitar tuning instantly became as simple as Strum – Tune – Rock! So how do you make the best-selling polyphonic tuner even better? You take it to the next level by providing multiple tuning modes, including polyphonic, chromatic, strobe and a variety of altered tunings; adding an onboard BONAFIDE BUFFER to preserve your tone over long cable runs and pedal board signal paths; and upgrading the LED display for even higher tuning accuracy. Say hello to your next tuner – POLYTUNE 3.

Whether you’re a mega-super rock star, a seasoned pro, or a passionate bedroom shredder, POLYTUNE 3 gets you in tune quickly and accurately. Depending on your needs, you can choose polyphonic for tuning all strings at the same time for your live gig, chromatic for more precision during a songwriting session, and strobe for the ultimate in precision when you’re laying down tracks.

POLYTUNE 3 includes the iconic BONAFIDE BUFFER, our renowned guitar buffer that ensures zero signal degradation – no matter how long a cable you need to run! Think of it as a tuner on steroids that constantly protects your precious tone.

Whether you’re performing on a truck bed in full sunlight, a dimly-lit tavern or a stage with a massive light show, POLYTUNE 3’s super-bright 109-LED display features an ambient light detector that automatically adjusts the intensity to provide the perfect readout.

POLYTUNE 3 provides high-precision tuning with just a quick strum, and the BONAFIDE BUFFER keeps your signal transparent and strong – no matter how many stomps you use, or how long your cable runs. Plus, you’ll have the most-versatile polyphonic tuner on the market right at your toes.
