Condition is grand.
Comes with box, manual, gator bag, keyboard stand. The stand and underside of the Korg have velcro on so it secures very firmly to the stand, handy for energetic gigging.
I have bought a new synth, stuck with Korg mind as I have been so blown away by this thing.
If you are unsure I will give you a demo of the amazing sounds it comes with, and that you can create. Pure evil, some of the things I've come up with, no joke.
Do some reading, do some tubing. It's bloody brilliant.
I think the price is very good considering what you get with it.
