compound radius ebony (since 2017) or maple fingerboard, in 4 and 5-string versions. The Mexican Deluxe Active Jazz Bass combines many of the features of the American Deluxe models with a traditional Standard Jazz Bass body, vintage-style hardware, a contoured neck heel and a 12"-radius 20-fret rosewood or maple fingerboard. It comes in 4 and 5-string versions and sports a three-band active circuit powered by two dual-coil ceramic Noiseless Jazz Bass pickups and an 18V power supply with an active/passive switch (as of 2016). The Custom Classic model was made at the Fender Custom Shop. This Custom Shop Jazz Bass was a cross between the American Vintage and the American Deluxe series. Features include an oversized select alder or premium ash body, a modern 34"-scale C-shape maple neck with an unbound rosewood, pau ferro or maple fingerboard featuring triangular pearloid block inlays and 21 medium-jumbo frets. Available in four- and five-string versions, all Custom Classic Jazz Basses came with a pair of custom-wound dual-coil Noiseless Jazz Bass pickups, a three-band active preamp, five-bolt neck plate, 18V power supply and a Deluxe string-through-body/top-load bridge with milled nickel-plated brass saddles. Models manufactured prior to 2003 (formerly known as American Classics) were identical to the mid-1990s American Deluxe basses in appearance, excepting the 22-fret bound maple neck featuring a rosewood fretboard and white block inlays. Fender discontinued the five-string version in 2009. The Custom Classic four-string Jazz Bass has been renamed Custom Active Jazz Bass as of 2010, featuring Fender's high-mass vintage (HMV) bridge and a 1960s Jazz Bass "U" shape neck. The Standard Jazz Bass model is sanded, painted and assembled in Ensenada, Baja California along with the other Standard Series guitars (replaced by the Player models in 2018). On December 5, 2008, the Standard J-Bass has given CBS era-style decals, a three-ply parchment pickguard and a tinted maple neck with rosewood or maple fingerboard (also available in a fretless version with a rosewood fingerboard and 20 inlaid white fretline markers). Other features included two staggered bi-pole single-coil pickups and a return to the black bakelite control knobs. Models produced before 2003 came for a period with black Stratocaster control knobs. The five-string version (introduced in 1992), available with pao ferro or rosewood fingerboard and a five-in-line tuner configuration with Gotoh Mini machineheads (c. 2006), has been updated with a tinted maple neck featuring a dark rosewood fingerboard and a 4+1 tuner
