14% price drop

I will be gradually lowering the price on this machine, Dutch-auction style, but feel free to send me an offer. No lowballs please.  If you would like to see this machine in person, get ahold of me: I am in Washington, DC.

This is a 10-voice Rev 3 Microwave XT Shadow, one of only 666 ever made.  I bought it earlier this year and used it to build Edisyn's Microwave 2/XT/XTk patch editor. It is a wonderful machine and I love it, but when I bought it I promised myself I would sell it at year's end, and so I am.

I think only three Microwave XT Shadows have come up for sale in the past decade.  Two of them were in the last few months, and both went for about $2K.  But they were in somewhat better condition. 

I rescued this unit from a basement cantina in Rome, Italy, a likely humid environment which caused, over the years, about 1-3mm cosmetic corrosion along the edges of the front plate, as can be seen in the pictures.  Now that it's stabilized in a decent studio environment it won't ever rust further, so I think the right thing is to sell it as-is rather than attempt some kind of restoration.  The corrosion is only on the edges: as can be seen in the pictures, the knob wells, screen, and internal electronics are all in excellent condition.  The unit works very well.

The synth also has a wiggly volume knob (a loose potentiometer shaft) which will go at some point.  It's still working fine for now, so I have elected not to replace it, but I will provide a Waldorf-sourced potentiometer (plus a set of buttons and encoders which you probably will never need).  Replacing the pot in the future is a trivial task on this machine for any competent technician.  The unit will also come with a brand new power supply sourced from Waldorf with EU and US plug options, plus the original (EU 220V) power supply which has a flakey barrel.
