PolyTune Clip Tuner : Top choice

The tc electronic PolyTune Clip Tuner is an incredibly convenient, fast, and lightweight way to keep your guitar in tune. I was initially torn between this model and the UniTune, but ultimately went with the PolyTune and couldn't be happier with my choice. The ability to strum all strings and instantly see any deviations from target pitch is a killer feature. The tuner's display is bright and stylish. My only wish is that the clip could be slightly larger and have more degrees of freedom, as it's difficult to adjust it for an optimal viewing angle without removing it entirely from the guitar. This can be a bit of a hassle when placing the guitar in a case, as the tuner needs to be removed and reattached each time. Overall, the PolyTune Clip Tuner is a top choice among tuners in this class.
