Roland SP-404SX Received from a friend. The pads, knobs, and other basic functions work without issue. Battery operation has not been tested. SD card is not included (due to security concerns). Includes power cable and the unit only. Free shipping via Rakuraku Mercari Delivery. I cleaned it as much as possible, but some dirt may remain. Please refrain from purchasing if you are concerned. Given the age of the unit, there may be crackling sounds when turning the knobs or moving the jacks. Also, please understand that this is a used item and is sold as-is, with no returns or refunds. No complaints, no returns.
