Volume control for harp microphones.
It's the perfect choice for the harp players that do not wish to alter their vintage mics by drilling and modifying the shell.
Volume control is compact and is compatible with any “screw on” (Amphenol) style microphone termination (i.e. Astatic, Shure, Turner...etc).
The potentiometer is 1 Megohm linear type, ready to be placed between your mic and your harp amp.
The brass knob allows for easy and precise adjustment of volume.
