The idea of the wood inlays were to reduce the coldness feel of aluminum. Usually but not always, the wood neck fills were the same type and color as the body. The Ebonol fretboard contained large Phil Petillo designed "center-touch" frets, a zero nut and aluminum dot inlays. The higher up models had the mother of pearl "crown" shaped inlays.
They were manufactured at the Kaiser Aluminum plant on East Avenue in Erie, Pennsylvania. The necks were attached to the body by two bolts and the bolts were covered by an oval shaped aluminum plate.
Control cavity covers were also aluminum. Some bass models were available fretless as well as half fretted/half fretless guitar.
