this device is build around a wsg-pc-board of ray wilson (http://www.musicfromouterspace.com/) but with a low power mod, which increases its sonic possibilities a lot. I have got some interesting rhythmic sequences out of it and complex drones of many different kinds. If you lower the power with the big knob right above you can create more noisy sounds, like a versatile noise generator.
I am happy with the results and after testing it thoroughly will sell it now, as it is my second device (but they never sound really similar).
It will set you back 190Euro plus shipping costs (which I will try to make as low as possible)
