Actually, I’m just jealous that they don’t have a version of the TunerMatic Action Tuner for ukuleles! The TunerMatic is a robotic guitar tuner. Just turn it on, place over a tuning knob, pluck a string and it will do the rest of the work. It will loosen and tighten the string till it is perfectly tuned. It works with both electric and acoustic guitars (acoustic guitars require an optional microphone accessory). The price seems very reasonable at only $49.95.
