Main unit, box, instruction manual. Operation confirmed with power adapter/batteries and SD card. (These are not included in what is being sold) Each button responds and recording/playback works without issue, but not all functions have been tested. Each terminal and knob is in good working order. The MIDI terminal has not been tested due to lack of compatible equipment. Dust will be removed with a duster, the unit will be wiped down with a cloth, and the terminals will be cleaned before shipping. *Please note that this item is also listed elsewhere, so it may be sold out if there is a discrepancy.
