This is a vintage Roland JX-3P analogue synthesiser.
The JX-3P is a fully analogue 80s synth stuffed full of those classic Roland sounds. Released around the same era as Roland's Juno series, the JX-3P was aimed as a more user-friendly analogue synth, packed full of presets and equipped with MIDI.
This used Roland JX-3P is in great condition, and sounds fantastic!
