ABSTRACT:
An attachment for a phonograph pickup cartridge capable of removing static and stabilizing vibration of the cartridge body. A brush comprising bristles capable of engaging the inside of the grooves of a disc-type phonograph record is coupled to the cartridge body through a bearing which provides a mechanical resistance capable of damping both vertical and lateral vibrations. The brush is made from an electrical conductor, such as carbon, and is connected to the shield of the cartridge to remove static electricity from the surface and grooves of the record.
