Fender FT-1 Pro Clip-On Tuner, Black

The FT-1 Pro is a straightforward clip-on tuner that does its job well. It uses a vibration sensor rather than a microphone, so it works accurately even in noisy environments -- on a loud stage, in a full rehearsal room, or at an outdoor gig. The LCD display is easy to read and the needle response is fast enough to tune quickly between songs.

It clips onto your headstock, rotates to a comfortable viewing angle, and stays out of your way while you play. It handles guitar, bass, ukulele, violin, and chromatic tuning. The build quality is decent and the battery life is good. Not much more to say -- it's a reliable tuner at a fair price, and every player should have one in their case.
