"The first commercially-available synthesizer marketed by Roland.
Works great, sounds great! There's a touch of key bounce detectable when "staccato" is selected, but I'm not sure that's abnormal.
All modules, sliders, switches, and presets are functional, and it's relatively quiet for its age.
The right wooden side-panel has come off, but it’s present and repairable. It's 48 years old, so the keyboard needs a good cleanup and calibration, but the keys, switches, dividers, and presets are all functioning properly, which I found amazing.
There was some tuner crackling ans static when I obtained it; the only servicing I've done was cycling the tuners until the crackling and static went away.
Everything is working smoothly, but with enough resistance to suggest that either lubricant-type solvent cleaner was used, none was used or that lubricant was replaced if solvent was used.
It came with a home-made hinged wooden case that was NOT form fit, and that case will be included with the sale."
