The Yamaha DX100 Synth. This is the 4th one I have sold and by far the cleanest. Tested and functions perfectly. This keyboard was made famous by Roger Troutman of Zapp & Roger for talkbox and is also used by P-Thugg of Chromeo.
It includes the original manuals and a catalog for this keyboard from the 80's. This will also include an original power adapter.
