If you defret the bass, PLEASE do your homework, read up on correct technique (hint: any recommendation involving a screwdriver or pliers should immediately be discarded) and take your time doing the job. Done right it will require 10+ hours of labor for a first-time project. Done wrong, you will have a hack job and chunks of missing fretboard.
There is plenty of info here on TB that can steer you into doing a good job that yields a great looking and professional appearing result.
