The resale value isn't great on pickups but if you must tinker, my thoughts are as follows. Fender don't make great pickups. They used to but something has gone wrong over the years that has allowed other market leaders to take over. (personal view). Fender pups are ok, but not what they used to be. Most pups on the market place are hotter, over wound and beef up the sound. I like a more retro / trad / vintage tone. From my experiences Wizard are great. The guy is friendly and helpful. However Seymour Duncan just pip it for me and offer a better quality pup. EBay has some NOS caps for sale for about a fiver and I have one of these in each of my basses bar one. If you want to replicate the vintage tones of your 62RI I'd go down this route. If you want it hotter, I can't say I have any experience. You could always try these mods and if it doesn't sound cool, EBay the new parts and stick the originals back in. Either way keep the original parts in case things do change and you come to sell the bass.
These sound amazing btw [url="http://www.seymourduncan.com/products/antiquity/bass/1104405_06_149/"]http://www.seymourduncan.com/products/anti...1104405_06_149/[/url] but don't come cheap
This is a decent upgrade [url="http://www.seymourduncan.com/products/basslines/vintage-1/sjb1_vintage_fo/"]http://www.seymourduncan.com/products/bass...jb1_vintage_fo/[/url]
All just my 2c and I don't suggest I know any more or less than anyone else. I have however changed pups / caps in five of my 6 Fender basses.
