Great Nord, used it for many gigs and remains the go-to for electric piano and B3 organ sounds. Maintained properly and tested for professional use. Pretty common for these to develop dings on the edges/corners, so I’ve included those in the pictures. This one will sell fast so good luck!

(I also have a gig bag for it, but the zipper situation is not good. It could potentially still be fixed up enough to use, so let me know if you’d like me to include that.)

Product Overview
The Nord Electro 6D 76-key stage piano elevates an already well-established keyboard to the next level of live performance. This keyboard features an easy to use interface with split and layering options, extended polyphony and so much more. With the combination of acoustic and electric pianos, sample synth, organ, and built-in effects, you'll be hard-pressed to find a situation where this keyboard is not the ideal solution.
