“Brilliant condition for its age with just a couple minor issue that can be easily addressed .
‘Data’ slider knob is missing. The ‘key assign’ and ‘cassette’ button don’t respond unless you press them a handful of times. This indicates to me that they simply need opening up and cleaning which would be an easy fix. Has a few marks and a small crack on screen by the ‘effects’ light indicator but is expected from its age.
Apart from that, the drum machine works brilliantly and can be hours of fun if you have a good look through the manual 🙂
Comes with brand new power adapter” Click here to visit listing on eBay
