"The Kramer aluminum neck era ran from 1976 to 1985 and was the legacy of the company before switching over to the more popular wood neck models uring the 80s. The first production batch of Kramers were introduced in November 1976. All of these early Kramers featured a "forked" aluminum headstock and aluminum "skeletal" neck (the Dukes had no headstock). These necks, designed for sustain, contained slots that ran the length of the neck for holding the wood fills in place. The idea of the wood inlays were to reduce the coldness feel of aluminum. The Ebonol fretboard contained large Phil Petillo designed "center-touch" frets, a zero nut and aluminum dot inlays. Scale lengths were 25". They were manufactured at the Kaiser Aluminum plant on East Avenue in Erie, Pennsylvania. The necks are attached to the body by two bolts and the bolts were covered by an oval shaped aluminum plate. Control cavity covers were also aluminum. Comes with OHSC.
