This is the KORG Pitchblack Advance PB-AD pedal tuner for guitar/bass. I am selling it to organize my equipment. I purchased it but never had a chance to use it, so it has been stored unused. I have confirmed its operation for this listing. [Brand] KORG [Condition] Unused [Included Items] Box, Instruction Manual Pitchblack Advance ±0.1 cent high-precision, color display, strobe tuning, true bypass, DC out equipped. Thank you.
