This is a Nord Drum 3P. I've owned it for a while but only used it a few times. The previous owner seemed to have only used it lightly too. It is fully functional and I never noticed any weird behaviors. Very solid beast of a drum synth.The volume-dial's knob has been replaced by the previous owner. The dial itself has not been modified at all, it's just a new knob. It does protrude a little more than the regular knob, as far as I can tell. I have reduced the asking price slightly, in light of this.I'll also include an unopened pair of red plastic drumsticks along with it.
