I purchased a loaded Fender Vintage Mod 2009 Jazz Bass. This is the loaded body only. Can any recommend a good playing feeling neck. Can anyone offer suggestion on good upgrades to the electronics. This is a passive bass. I have owned mostly actives in the last 5 or 6 years and considering upgrading this right out of the box. I am also considering a BAD ASS bridge upgrade. Does anyone have experience with these bridges and what (if any) advantages these bridges offer.
