Discussion about the Korg PolySix synthesizer

Some pictures: http://www.drni.de/niels/for-sale/tridentmk2/

In case you're interested, write personal mail. Please do also give
country,  city name, and postal code, this will enable me to find a
shipping company with a good price. The whole thing (Trident + Case) is
approx. 36kg which makes it more difficult.
