I've got an early '90s Fender Jazz Plus V, and it's a nicely built instrument. However, I've never like its sound, or its playing response, so I'd like to use it to experiment on. I'm aware that Fender J pickups (and those from various manufacturers) can have some different dimensions from the neck to bridge unit, with the neck p/u being a little narrower than the bridge. Does anyone know (without me yet measuring the actual dimensions) if this bass has same size, or different size pickups, and if I were to want to put current generation Fender Noiseless units in, would they both fit? Also, what p/u makers have the units available in sizes that would fit. Another thing: Does anyone have an opinion whether the pickups or the pre-amp would be a better bet to replace on this bass? I'm toying with the idea to try and hook up the pickups with a jumper, bypassing the pre-amp, just to see if I like the sound better (they're the Fender/Lace Sensors), and the pre-amp is the one similar to the Kubicki offered around the same time, although I don't know if it's the same. This issue may be something that is a known been there/done that kind of thing, which is why I'm asking. I'd just like to get a more "Fender Jazz-ish" kind of tone out of it. Thanks for any advice.
