Tested and confirmed to be working. It's relatively clean for its age. The F key in the middle is slightly lower, but there were no issues with velocity output. Original box included (shows signs of use, dents, and damage). AC adapter included. I am also listing other synthesizers and recording/PA equipment, so please consider those as well → #MemekurageSynthesizers #MemekurageRecordingEquipment #IncludesShipping #MusicalInstruments #InstrumentsAndEquipment #KeyboardInstruments #Keyboards #MIDIKeyboards #Synthesizers #DTM #DAW #YAMAHA #Yamaha #CBX
