This is one of a kind in Vienna: owner and guitar craftsman Michael Eipeldauer restores and sells 'contraguitars', also known as a Schrammelguitar. They're used for folk music, jazz and other styles, and have a standard neck plus a second fretless one for bass notes. A prized piece is a Biedermeier model from the 1840s.
Secondhand East German guitars, such as models from Musima and Artur Lang jazz guitars, glisten on stands around the store.
