I purchased this tuner to use with my Ukulele that doesn't have pickups. Until now I had only ever used tuners with line in, or a microphone, so this is my first tuner that works only on vibrations.
The tuner clips to the headstock of the Uke, picking up the vibrations from the strings, and I was surprised at how accurate the tuner is. There is a slight delay between changing strings and the tuner recognizing the new string, this is why I give it only 4 stars, but the result is very accurate.
It includes 3 modes, Chromatic (where it recognizes any note), Ukulele C (which recognizes the string and tells you what it should be tuned to for C tuning) and Ukulele G (which again recognizes the string and guides you to a G tuning).
The tuner is light enough to be able to leave it attached to the headstock without it causing too much neck dive, which would make it uncomfortable to play.
I reccommend this tuner because for the price, it does everything the more expensive tuners do!
