Previously Munky shared the K7 Korn signature model with his former bandmate Brian "Head" Welch. The K7 was discontinued in 2006 in favor of the APEX models. The APEX1 is based on the RG series body shape. It features a mahogany body mated to a custom maple and wenge neck with a 24-fret bound rosewood fingerboard with special inlays. Components include dual DiMarzio PAF 7 pickups, Gotoh tuners, a locking nut and a double locking tremolo bridge with the special U-bar which is a continuation from the K7. The APEX2 is a similar model built for a lower price point.
