We have this (NOS) Korg AW-1 tuner in-stock and ready to be shipped!
The Korg AW-1 is one of the most convenient tuners available. Small enough to fit in your pocket, you can clip the AW-1 easily onto virtually any instrument. In fact, the LCD meter display can switch from horizontal to vertical, so you can position it on the instrument in whatever way is most comfortable for you. A piezo pickup actually detects vibrations from the attached instrument, or you can rely on the Korg AW-1's built-in microphone.
