The Flatsons FT3 is a compact, rechargeable clip-on tuner designed to provide fast and accurate tuning for a wide range of stringed instruments. Its high-definition colour display provides clear visual feedback, with intuitive colour indicators showing whether your note is flat, in tune or sharp.

With dedicated Chromatic, Guitar, Bass, Ukulele and Violin modes, as well as open and descending tuning functions, the FT3 offers versatile tuning options in a small, portable format. Its clip-on vibration sensing allows for noise-free tuning, making it suitable for use in practice rooms, rehearsals and other environments where background sound may interfere with conventional microphone-based tuning.

The tuner features a rechargeable 180mAh polymer lithium-ion battery and USB Type-C charging, eliminating the need for disposable batteries. The adjustable clip and viewing mechanism also make it easy to position the display for comfortable viewing from different angles.
