JT30VC

A superb omnidirectional crystal microphone used by discriminating Harmonica musicians. The JT 30VC’s high output crystal element has been factory tuned to provide just the right presence or “bite” to create the ideal sound for blues and many other styles of play.

The rugged JT 30VC has a die-cast zinc housing which is “cup shaped” for a comfortable fit in the palm of the hand, and the JT 30VC includes an easy to operate volume control. It is elegantly finished in a non-reflecting black urethane paint with a brass plated grille.
