One of the biggest reasons to buy this pedal is the phenomenal display. Your settings are recalled when you turn the pedal off and on again, which is nice. A TUNING switch cycles through various tuning modes from standard, to alternate, to capo (first through seventh fret), and holding down the foot switch for 3 secs puts you in drop D. The inclusion of a strobe tuner is great for touring pros and if you need hyper accuracy ( +/- 0.1 Cent tuning accuracy to be exact). The DISPLAY button on the back of the pedal cycles through guitar needle -> guitar strobe -> bass needle -> bass strobe. We’ve established the pedal looks and feels good, but the big question is how well does it tune? The answer is extremely well. This isn't critically important, but it shows TC wants to make updates and improvements available for guitarists who make the investment in this pedal. Here's one of our favorite features - on the back is a micro USB port for firmware updates from TC Electronic.

The input/output jacks are on the left & the right, and on the back you have a 9V DC power input (power supply not battery are included) and a power output, so you can use the PolyTune 3 to daisy-chain and power other pedals (current draw of other pedals not to exceed 2000 mA). When the PolyTune 3 is on, the output is muted so you can tune up quietly. You can also set the pedal to Buffered Bypass via 2 DIP-switches underneath the bottom plate (might be necessary if you have a super long cable between your guitar and first pedal, or you have a ton of pedals on your board). This pedal sports True Bypass, meaning when it's off it won't influence your tone at all. The soft-click footswitch is always appreciated.

It’s got a solid metal enclosure and is definitely road-worthy (evidenced by the many big names that take this pedal with them on tour). The PolyTune 3 is slightly narrower than a Boss stompbox, taking up a bit less real estate on your board. The PolyTune 3 has a sleek minimal design, impressively bright screen, and all the tuning features you could want in a tuner pedal. TC Electronic has really taken the fight to Boss when it comes to an industry standard tuner pedal. The PolyTune 3 is going on my pedalboard. This pedal’s minimal & clean design wins me over.
