Thank you for viewing. I purchased this item at the same time as the JVM410H, but I am selling it because I have introduced a MIDI-compatible switcher. I was using it until recently. Operation has been confirmed. I have used it a few times in the studio, but please refrain from purchasing if you are overly concerned about its condition. No returns or exchanges, as a measure to prevent product substitution. Please feel free to ask any questions you may have!
