Are there any manufacturers making black Fender jazz pickguards? I don't believe Fender makes them in that color, and I have not been able to find one in stores. Also, I'm thinking about changing the tuners on my Geddy Lee jazz to some lighter ones, due to its neck heaviness. Would this solve the neck dive problems? Any recommendations? Out of all the Fender jazz basses I've played, the Geddy Lee is the most neck heavy. Is there any particular reason for this? Thanks for any info you can provide me.
