"Note: All Model 101 key contacts we have seen in recent times have been worn out to some degree. This unit is probably no exception. What this means is that, even after a proper cleaning, keys may sometimes re-trigger. If this bothers you, we recommend using an external CV and gate source such as another keyboard, a MIDI to CV converter, or a CV gate sequencer.
Like nearly all the high end vintage analog synths we sell, this item has been METICULOUSLY disassembled, cleaned inside and out, FULLY serviced by professionals who’ve been servicing and selling vintage synths for more than the last 2 decades, and systematically tested multiple times over a long period to ensure it’s working exactly as it should. No BS. No ebay surprises. We’re perfectionists and don’t cut corners. Although this instrument came to us in relatively good shape, we want our items to be better than the rest and invested *many* hours of tech time plus parts costs to fully overhaul this unit so it would be clean, working like new again and as reliable as possible for its next owner. This was a serious investment of time, love, and money, and was definitely worth the effort and is of course reflected in the higher than usual price. If you’re looking for a great sounding example of this model that works just like it should without needing to invest hundreds or thousands of dollars in tech fees and waiting from weeks to years, this one should make you very happy."
