This week I visited Musik Productiv, one of Germanys largest music stores. It is in a massive (Costco size) warehouse but it is in the middle of no where. So clearly, people who visit are definitely there to buy something.
It is an extremely impressive store. This video shows only one part of the store, the guitar section. There are 6 other sections all as large as this area.
