Works confirmed. Box and instruction manual included. I purchased it in excellent condition and used it for a few weeks, but it didn't suit me, so I'm selling it. It's an easy-to-use and easy-to-see tuner. Limited color. This is the KORG Pitchblack Advance pedal tuner, which achieves high-precision tuning. - Brand: KORG - Model Name: Pitchblack Advance - Type: Pedal Tuner - Accessories: Instruction manual - Condition: Unused Thank you for viewing.
