JJ Harp Mic (Jürgen Morgenroth)

About JJ Harp Mic

JJ Harp Mic is a one-man operation run by Jürgen Morgenroth in Düsseldorf, who for around four years, alongside his band activities, has been working with US bullet microphones and matching elements. The offering includes customized bullets for the blues harp, conversions, repairs, spare parts as well as Shure CR/CM elements and Switchcraft/XLR adapters. According to its own statement, the aim is the design and conversion of microphones that support the traditional Chicago blues sound. The website shows numerous examples of converted and brokered vintage microphones such as the Shure 520 (1949/1950), Shure 707A and Astatic JT-30, as well as custom work. It is a privately run hobby and small business without industrial production, certifications or machine details. Its customer base is the blues and harp scene; BB & The Blues Shacks, among others, is mentioned in this context.
