The Fender Jaguar Baritone Custom or Jaguar Bass VI Custom is a retro electric bass guitar manufactured in 2005 and 2006, based on the 1964 Fender Jaguar electric guitar and the 1961 Fender Bass VI electric bass guitar.The Baritone Custom's standard tuning is E to E, one octave lower than a standard guitar, using the same string set as the Bass VI (25-35-45-55-75-95), but with a slightly shorter scale length of 28.5 inches, as opposed to the Bass VI's 30 inches, giving the Baritone Custom slightly less string tension.
