Have a look Fasanenstrasse/Pariser Strasse, shop is called Sound&Drumland (Underground U1 or U9: Spichernstrasse). Look for Studioland in Fasanenstrasse. And have a look in the area of the Alexanderplatz (many ways U,S,Tram, bus - no problem).
And not to forget: Have fun here! Buy magazine Tip or Zitty (14 day periodicals, one week this one to choose, next the other one). A day includes the evening... Sorry, but 2-3 evenings, not really enough...
