Design Classic – The Blues Harp

In the mid-1990s, Hohner introduced a series of interchang- eable parts known as the modular system, usually abbreviat- ed MS. The Blues Harp has been around since the early 1970s. The songwriter Johnny Cash promoted Blues Harp and in the 1990s, Hohner made Blues Harp part of his Modular System (MS) line. Today it remains one of the most popular instru- ments for MS harp players.
