Tuning modes
Let's start with the two separate chromatic tuning modes, which cater to your individual preferences and needs. Needle mode is for those that are used to the classic view on a tuner. For the people that want a little more real-time information, we have included stream-mode, which measures even the slightest pitch variation and instantly feeds the info back to you via a rotating motion on the display.

Tuning Magnet
Key to both these great chromatic modes is an ultra-fast and precise response, which is achieved via the use of the unique tuner magnet feature. This slows down the needle once you get close to the desired pitch, making it much easier to get the job done quickly.

PolyTuneTM features "MonoPoly", a unique patent-pending technology that recognizes whether you play one or more strings and instantly replies with the appropriate poly- or monophonic tuning mode.
