in conjunction with famous players and the first signature Jazzmasters were introduced in 2007, Kurt Cobain's signature Jaguar was introduced in 2011 (20th anniversary of the release of Nirvana's Nevermind album). In the past, a Kurt Cobain replica Jaguar was made for the Japanese domestic market. The Fender Jag-Stang, a Mustang/Jaguar hybrid, was built for Kurt Cobain based on his design. In May 2008 Fender introduced the Classic Player Series Jaguar and Jaguar HH with dual Enforcer humbuckers, which are made in Mexico and sold for under $1000. Fender have made numerous changes to the classic design, however, replacing the bridge with a Tune-o-matic type, giving it a 9.5" fretboard radius, moving the vibrato unit plate closer to the bridge and installing high output pickups. This Classic Player guitar is also available as a "1966" limited-edition version with a bound neck featuring rectangular block inlays and CBS-style decals as of 2009. In September 2010 the Black Top Jaguar HH was introduced as part of the Mexico-made Black Top series. Features include a solid alder body with gloss polyester finish, chrome hardware, dual Hot Vintage AlNiCo humbucking pickups with chrome metal covers and black skirted amp knobs. Other refinements include a maple neck with a 9.5"-radius rosewood fingerboard, 22 medium-jumbo frets, 24"-scale length, a stop tailpiece and a three-way toggle switch. Features The Jaguar was built from ideas first incorporated in the Jazzmaster, with a similar "offset waist" body and vibrato unit. Unlike the Jazzmaster, the Jaguar was fitted with a shorter 24-inch scale, 22-fret neck and featured smaller single-coil pickups with notched side plates that improved RF shielding, making the Jaguar less prone to interference than the more popular Stratocaster and Telecaster. The Jaguar and the Jazzmaster also shared a dual-circuit setup, one circuit for lead and another for rhythm, each with separate controls, allowing for two preset tone and volume settings between which the guitarist could rapidly switch. The Jaguar, however, had a more complex lead circuit consisting of three switches and two dials on the lower bout: the first two switches were on/off switches for the neck and bridge pickups, respectively, while the third switch engaged a capacitor that served as a high-pass filter (sometimes referred to as a "strangle" switch). The rhythm circuit, set into operation when the upper bout switch is flicked upwards, had individual volume and tone rollers but no option to choose between pickups.
