With its signature green and chrome die-cast casing, the 520DX "Green Bullet" holds a spot in history as the definitive blues harp voice.
The 520DX features a volume control knob at the base of the microphone that allows users to make adjustments to suit their needs during live performance. An attached cable with a standard ¼-inch plug allows the microphone to be connected to a high-impedance device. Contoured to fit perfectly between harmonica and hands, it can also be used for distinct, lo-fi vocals.

About Dynamic Microphones at Sound Productions
If you’re looking for an all-purpose, heavy-duty microphone, look no further than a dynamic microphone. Equally outstanding in both the studio and live on stage, dynamic mics are an affordable, versatile, and classic option for nearly every miking application. Popular uses include live performances, studio recordings, man-on-the-street style interviews, as well as podcasts that aim for a professional “radio voice” polish.
Dynamic microphones work using a coil attached to a magnet. When sound waves cause the coil to vibrate up and down against the magnet, an electromagnetic current is induced; in simple terms, this turns the sound into an electronic signal to be channeled into a recorded version or—in the case of live sound—into a speaker to distribute the sound to the audience.
