I have a beautiful 2005 Fender American Deluxe 5 swamp ash vintage cherry burst Jazz bass that I bought new (mail order thru MF). When it arrived I was very dissapointed by the sound of the bass. Looks, fit, finish, hardware, neck and body were all fantastic. The pickups and preamp just didn't do a thing for me. So after paying over $1200 for the bass I sunk over another $600 in it to replace the noiseless pickups with Barts and the preamp with a John East deluxe. That and a string change to LaBella tapewound made a huge difference in the sound of the bass and brought it to the point where I really liked it.
A couple of years later I decided I wanted to try my hand at a bass spec and build so I worked with Warmoth to find a really lite Jazz 5 body and solid Indian Rosewood neck. I again with with John East for a custom designed preamp to my specs and slapped all gold hardware, gold frets and a brass nut on the bass. The result was a custom designed 5 string bass with a P/MM pickup configuration that cost me a little over $1500 (almost $500 less than my MIA Fender deluxe 5 jazz). The Warmoth bass, looks just as good, plays just as good, feels just as good and sounds even better than the Fender and cost me a lot less.
When people see them side by side I get lots of complements on both but more on the Warmoth. When I play them I get nothing but complements on the sound of the Warmoth, not much of any reaction when I play the Fender.
My advice, if you're going 5 string, go Warmoth and plan on about $1500 total cost give or take a hundred. You'll end up with exactly what you want and it most likely will be a keeper (which is a good thing because you'll never get more than $500 at most for it if you decide to sell it). I'll have mine forever, not because of the low resale value but because of the high quality and fantastic looks and sound.
I'll see if I can find a pic of the two basses together to post.
