I have been using the Snark Clip-On Chromatic Tuner for years and it is a must have for musicians of all skill-levels! I always recommend to my students that they get one. It is an easy-to-use, invaluable tool that will ensure that your instrument is in tune every time you play. The display is easy to read and very clear on whether the pitch is flat, sharp, or just right and because it is a chromatic tuner it can be used for any and all instruments.
