This recently serviced Roland is a great example of a great synth without it's fatal flaw. The red glue has been removed! The faders have been cleaned as well, making it smooth sailing to surf patches. It sounds amazing with plenty of tonal opportunities unlike any other synth. For the casual keyboardist, it may not be the easiest to learn, but the excellent presets cover a lot of ground. But for synth lords, the knob per function layout will be greatly appreciated.
