Fender Jaguar Bass - Kitmonsters The Fender Jaguar Bass is similar to the switch-laden Fender Jaguar guitar first made in 1962, but has a slim Fender Jazz Bass-style neck, bridge, and pickups. With so many controls, it is a hugely flexible instrument that can give you everything from growly to bright tone, and features a preamp with bass and treble boost options.
