This is an aggressively styled guitar named after ‘King’ Robbin Crosby of Ratt. The V-shaped design spawned from a custom Jackson he’d play, a ‘Double Rhoads’ (a V guitar comprised of the ‘long’ wings of a Rhoads. This was never a regular production model). Later Dave Mustaine would be the face of this guitar among others. The King V was designed as a smaller version of the Double Rhoads to accompany more average sized players. These guitars are traditionally two humbucker designs with a tremolo, but not always. Other design specs vary as well, such as 24 or 22 frets, knob/control configurations, the fretboard, etc.
Early USA King Vs we’ll briefly touch on from 1985. The Custom would have the ebony fretboard option with biding and sharkfin inlays. Pickup and bridge could be whatever the customer chose. The Student offered a rosewood board with dots and no binding. Neck-thru designs. From the 1989 Jackson Catalog image there appears to be 22 frets, but perhaps this could be customized.
