Boss TU-2 Tuner Pedal (Second Hand)

This pedal is used but still in excellent working order

The BOSS TU-2 Chromatic Tuner incorporates BOSS' world renowned TU-Series tuner technology into an ultra-convenient stompbox design. For the first time ever, guitarists and bassists can now tune their instruments with unrivaled accuracy and an unmatched tuning range--with just a single stomp.
