The perfect pitch that musicians always want - on a key chain! The Pocket Tones is a handy, durable, and compact device that can be carried in your pocket or purse on a key chain or can fit conveniently in an instrument case to provide accurate tones whenever you need them. Use Pocket Tones to develop excellent pitch recognition – it is the perfect answer for an immediate tone, and it is always at hand. The Pocket Tones Mandolin and Violin Tuner provides four electronic reference tones matching the four strings of the mandolin or violin. Batteries included (AG13). Shuts off automatically after 30 seconds. (Warning: Because of its small size, the Pocket Tones tuner is not intended for young children.)
**NOTE: This is just like a traditional pitch-pipe.
You will need to be able to match the string to the tone by ear to use this.
