It seems with clip on tuners that everyone in the world is making one. There is a baffling array of shapes and sizes. A former favourite of ours was the Snark, but we've now settled on a preference - the Clippon Tun05. This works in the same way as a Snark, with a similar display. But the Clippon is lighter, more compact and the display is brighter. It works with all instruments and is fully chromatic with tuning modes for guitar, bass, violin and ukulele. It also has pitch calibration.
