My parents are going to Germany and I want them to get me a pair of Seymour Duncan Blackouts for my Ibanez RG7421. I wanted to know what stores are similar to GuitarCenter, as buying them online won't work (they will be a couple of days in varios cities, not only Germany, so they can't wait for shipping, plus they are kinda stubborn about that)

Also, if someone knows any good record stores (specially the ones that sell various metal albums and not just the popular ones) that would be awesome.

The cities they will be visiting are Munich, Berlin and Lubeck
