While anyone can buy a Fender or assemble parts together, mine are different. Among other things, I copper foil shield the pickup, pickguard and electronics cavity, level the frets, roundover the fretboard edges, polish the frets and give it a complete set-up, all while installing quality parts and electronics that you would normally have to purchase and install in addition to your bass. In the end, you end up with a bass that you'd pay hundreds of dollars to a guitar tech to do all these things (in addition to the cost of the instrument). The value is in the details.
Bass with no case: $
