The guitar shown in the images is an authentic 1966 Fender Jaguar finished in its original 3-Tone Sunburst. The serial number stamped onto the neck plate (165620) firmly verifies its manufacture year as 1966, placing it right in the highly desirable CBS-era transitional period. This specific instrument showcases premium mid-1966 aesthetic milestones, including the transition to pearloid block inlays and white neck binding, while maintaining the classic multi-ply tortoiseshell pickguard. SpecificationsBody & Construction
