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.
w/ Black Body/Polished Nickel Grill
w/ Lundahl LL2912 Transformer Single Short Ribbon
w/ Radian Grill
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.
