Operation confirmed. Accessories include only the main unit and power cable. This is a SONY rack effect unit used by guitarists in the 90s. It's a large and heavy effect unit, but it produces a unique sound that only it can deliver. [Description] The SONY DPS-M7 rack-mount effect unit is a device that compiles modulation algorithms still used in recording studios today. It was a popular piece of live equipment in the 90s for guitarists such as Takahiro Matsumoto of B'z, INORAN of LUNA SEA, and Hisashi Imai of BUCK-TICK. Please comment if you have any questions.
