I'm selling two vintage Korg synths, Wavestation and DW-8000, both full synths with keyboards not modules. I am selling as is, the Wavestation I believe needs a new display (it buzzes) and the DW-8000 needs a replacement battery. So both need service. So sold as is for parts or to fix. Both are in good condition otherwise, small signs of wear, kept in cases in storage, both have power cords. What is a fair price for pick up? I'm in the US WA state.
