I must admit that I have never found the need to change anything on any of the Fenders that I own. I like the way they sound just fine. I wonder sometimes if impressionable players get caught up in a 'you need to mod your bass' mindset. I also agree that an amp plays such a vital part in the sound of the bass, a fact that can often be overlooked. However, if a player really feels that a different pup, bridge, etc will make their bass sound the way that they want it to sound then why not?
