Antique Copper Finish w/ Stock Transformer

The Knuckle Head is a passive ribbon microphone that combines the acoustic components of the successful Fat Head ribbon with a shockmounted headbasket design reminiscent of early broadcast microphones.

The ribbon motor uses Neodymium magnets surrounding a 2.2-micron corrugated aluminum ribbon measuring 5mm x 45mm. The ribbon is mounted symmetrically within the magnetic gap, making the Knuckle Head suitable as the mid mic in a MS setup — the front and back of the mic should produce the same sound.

The ribbon motor and headbasket are suspended within a 6-inch diameter metal hoop by eight springs. The output transformer is located within the cylindrical shaft below the shockmount hoop.
