Never misplace your tuner again with the Seiko Chromatic Tuner Keychain. This tuner is small enough to use as your keychain fob, so you can always have it with you – even sitting around a campfire with your favorite travel uke. It has a range of A0 to C8, and it indicates “note deviation in 1 cent increments”. It has a built-in microphone to listen to the notes as you pluck the strings, and to save battery, it will automatically power off after two minutes of inactivity. The Seiko Chromatic Tuner Keychain is available for $16.50 at Peripole in the US and for $14.99 at L.A. Music in Canada.
