Congrats - great units and nice to a see a mint one like that! I have two old Roland SDE-3000 delays that I use in my W-D-W setup and those old PCM-41s are the only thing that competes to me.
One of my SDE-3000s recently died though. Intermittently, the screen just flashes across and there is no output. It's been in a Roland repair shop for over a month and no fix yet. Real bummer!
