Thank you for viewing. This is a Korg Pitchblack Plus. I'm selling it to declutter. With its outstanding visibility and ±0.1 cent accuracy, the sound is noticeably different from a simple tuner. There are no noticeable scratches on the main unit, but there are some tape marks because it was attached to a footboard. Please refrain from purchasing if you are concerned about this. Main unit only. Instant purchase is welcome. Please feel free to ask if you have any questions!
