the visual style of the guitar slightly making it distinct from all other Jazzmasters. While altering the visual style, the relocate tailpiece solved two of the critical design flaws in the original guitar by increasing the break angle over the saddles and increasing clearance over the tailpiece's domed screws. This relocated tailpiece has remained in the Mexican Jazzmaster line ever since. Fender also installed special designed P-90-type high-output single-coil pickups. These P-90 pickups operated with a bar magnet at the base instead of the magnetized polepieces of the original pickups. September 2010 saw the introduction of the Mexican-made Black Top Jazzmaster HS. This guitar sports a Duncan Designed single-coil Jazzmaster neck pickup and a hot vintage alnico humbucking bridge pickup, with other distinctive touches including skirted black amp knobs, a Jazzmaster tremolo tailpiece (without locking button) and a three-way toggle switch. Other features include an alder body, maple neck with 9.5"-radius rosewood fretboard, 21 medium-jumbo frets, gloss polyester finish and chrome hardware. The Jazzmaster Standard was evolved from the Blacktop model. The Standard featured two coil-tapped Blacktop humbuckers and a Pau Ferro neck; often mistaken for Rosewood. Outside of these changes, the Standard had identical specs as the previous Blacktop model, including the relocated tailpiece. Despite numerous modernising design changes, the Standard shipped with a vintage bridge, long lambasted for its instability and frequency to buzz. This caused many customers to replace the bridge with a Mastery or Staytrem after market bridge. The Player Jazzmaster replaced the Standard in 2018. While specs remained similar, the neck was extended to 22 frets, pickup rings were replaced with scratchplate mountings and the humbuckers replaced with more 'vintage' voiced models. Knobs and other plastic details (excluding scratchplate) were switched from black to white. Fender USA In January 2013, Fender added the Carved Maple Top Jazzmaster HH to its premium Select series. The instrument features an alder body with a carved maple top, a pair of new Wide Range Special humbuckers controlled by a three-way switch, volume and tone (with push-pull S-1 switch), and an Adjusto-Matic bridge and tailpiece arrangement. It also features an innovative "channel-bound" rosewood fingerboard, in which the fingerboard itself is inlaid into the maple neck. In 2016, Fender released a "Limited Edition American Special Jazzmaster" which featured stripped-back controls and a Bigsby B50 tremolo/tailpiece instead of the traditional Jazzmaster tremolo/tailpiece. It also had a different type of bridge. In January
