One of the most friendly people you can meet in this world is Andreas Schneider. If you go to his synth store in Berlin he will enthusiastically show you all his toys and then set you free to play with everything. When I lived in Berlin I bought a few things when the store was at Alexanderplatz. Now they have moved to Kruezberg and lucky us Musotalk has uploaded a video showing us the new place.
“Our showroom in Berlin .. is called Schneidersladen now at the Kottbusser Tor above ‘Kaisers’ with quite limited opening hours: On Mon, Tue, Thu, Fri 2pm til 6pm you are very welcome, wednesdays the showroom is closed (!).”
