Roland Lucina AX-09 Keytar Synth
Personally, i'd just buy this for the "Jazz Scat" preset. But there's a tonne of fun sounds onboard.
Great overall condition and works perfectly. Japanese power supply included (will need a stepdown to use this) but works perfectly on batteries or the Australian power supply is readily available.
