Fender bass introduced the Dimension IV Bass (and its five-string version the Dimension V) in 2004. The two Dimension models were designed as a more contemporary alternative to the iconic Precision and Jazz. The Dimension basses were player’s instruments in the $1,000 range, and while they certainly weren’t the first Fender basses to have two-octave necks, active circuitry, no pickguard and tuners on both sides of the headstock, they were unusual among Fender basses of any era in that they had tilt-back headstocks. The Dimension IV and V were solidly built, smooth-feeling, good sounding instruments but they never really caught on and after three years, they were discontinued in 2007.
This was a completely different instrument to the Fender American Deluxe Dimension IV - which is made in the USA and has a pickguard.
