Body only. Power adapter/batteries and SD card operation confirmed. (These are not included in what is being sold) Each button's response and recording/playback worked without issue, but not all functions have been checked. Each terminal and knob are also without issue. The MIDI terminal has not been confirmed as I do not have compatible equipment. Dust removal with a duster, wiping with a cloth, and simple cleaning of the terminal parts will be done before shipping. *Please note that this item is also listed elsewhere, so it may be sold out if there is a discrepancy.* Zoom ZOOM Multitrack Recorder MRS8 Brand: Zoom (Musical Instruments)
