I bought this 2yrs ago new, set it up played it a little. Then I got a puppy, put it on a table for 1 1/2 yrs. I was worried about the pup chewing on the cables (he never did).
Anyway, I want to sell it now. I put it back in the original box and there it sits.
All cables, hardware, wrench, cymbals, foot pedals and drums are there, plus a pair of sticks.

It did not come with a manual, just a poster sized diagram.
