Roland U-20 synth
I'm not really a synth guy, but I have a few around. Funny how often this and the Akai ends up being used on records, rarely as a centerpiece but sometimes just ambient or a particular part. This also works great as a MIDI controller for some of my software synths. I actually scored this from Dale Turner, who used to live down the street from me, when I helped him upgrade his MIDI setup from Amiga to windows.
