I have an OP-1 which I bought a couple of months ago, in perfect condition, no bumps or scratches and still in the box.
I do not have the time to invest into this great machine, so it makes sense for someone else to enjoy it.
I also have a MicroKORG that I am selling, almost new, in box with power supply and MIDI cable if you are interested.
I am in Sydney, Australia. Please let me know if you are interested and let me know how much you are willing to offer for the price [no trades please].
As I do not check this forum, please contact me at zero dot sakura at outlook dot jp
