The reason that one would put another $400 (not near what I paid for the Nord 2-band I put in my Elite at the time, but I digress, I suppose) is that while I thought the OEM Elite preamp sounded pretty good, I found myself wanting a different tone than what the OEM preamp was giving me. Can't speak to the needed neck work. And a few months into the Elite, I discovered that I needed more thorough shielding in it. Took an hour one night, added some shield foil, much easier and cheaper than trading basses (although I will proclaim loudly that Fender's shielding work sucks)
Some of us can build parts basses to our tastes and specs. I could and maybe I should, but at my age, I just don't wanna. At the time, I found the Elite Jazz 5-strings to be great-playing basses and a preamp swap (and later, hold onto yer hat, pickups) was worth the trouble and expense. Then I discovered Mike Lull basses....
This thing of "just sayin' doesn't work too well with me. We all have different tastes and needs in basses and if we have the means, who should care if I want to spend more money on an expensive bass to tailor it to my wants and needs?
And if that sort of thing bothers, you don't EVEN want to know what I did with the OEM pups and preamp in my
Mike Lulls....
