Taking cues from the major-league success of the previous PolyTune Mini, the PolyTune Mini 3 is a guitar tuner pedal designed to make your tuning experience easier, quicker and more accurate - all while taking up less space on your pedalboard. It’s a pedal packed full of useful features, including different tuning modes, switchable true and buffered bypass and more. With this set of features, it’s easy to see why the PolyTune Mini 3 is a firm favorite amongst electric guitar and bass players of all styles and ability levels.

Out of the box, the PolyTune Mini 3 is reassuringly heavy for a mini pedal. It feels solid and durable, giving us great confidence in its ability to withstand the road-wear we’ll be subjecting it to. Like all other TC Electronic pedals, the casing is a solid-metal affair, so our ‘affordable pedal’ nerves are calmed from the get go.
