Last updated on June 11, 2024 8:29 pm Details


In this review post we’re going to be discussing the TC Electronic POLYTUNE 3 MINI Guitar Pedal Tuner, including an overview of its unique features.

Product Description

Carrying on the POLYTUNE legacy, POLYTUNE 3 MINI packs an unprecedented amount of tuning power into a tiny footprint without sacrificing essential features, such as always-on mode and our audiophile BONAFIDE BUFFER circuit for uncompromised tones – making it ideal for fully-loaded pedal boards where every inch counts!

Is your signal in desperate need of a strong buffer circuit to save your tonal integrity from a platoon of hungry true bypass pedals? POLYTUNE 3 MINI has you covered for any setup, and then some. Thanks to its built-in BONAFIDE BUFFER, which ensures zero signal degradation and an extremely high signal to noise ratio, POLYTUNE 3 MINI is the ultimate 2-for-1 pocket tool for pedalboards – keeping your tone robust and your pitch in place. Switch off the buffer, and you’re instantly back in true-bypass mode.

When you’re on stage rocking out, there’s just no time to stop and tune up, even if you’ve gone a bit overboard with the whammy bar. With POLYTUNE 3 MINI’s always-on mode, you never have to miss a beat. Additionally, there are 2 very practical DIP switches mounted on the side of the pedal that make it easy to go from buffered bypass to true bypass, and from standard mode to always-on.

Whether you’re performing in direct sunlight, under a massive light rig or just planning to be the first live artist on the surface of the sun, the bright display on POLYTUNE 3 remains clear and readable. And with 109 powerful LED’s running at full blast, you won’t have to search for the display – it will find you!
