For those looking for a teacher around Zurich, try
http://www.guitar-school.ch/e_index.php I had my first lesson there last night, nice studio, easy to get to and Tsering seems to be a nice guy.
I turned up a little early so I could watch and listen to the end of the lesson before me and have now signed up for 10 lessons. Will see how it goes after that but I have a good feeling that I've found a long term teacher.
Oh and if you do go, it would be nice if you mentioned that you heard of him through Adrian.
