I was considering having my CV Bass VI refinished, but decided not to put that kind of money into a Squier. I'm 100% confident that I can make a better Bass VI body and neck myself, once I get my shop up again. This body has some decent grain anyway, so I don't mind leaving it alone. But, I still wanted to spruce it up a bit, so I decided to go more 70s, with a black guard. The first vintage Fender I ever played was when my buddy in HS bought a 70s Jag with a black guard. This looks a lot like that, sans the warped pickguard.
I also removed the overwound stock bridge pickup, putting the middle pickup there, to get RW/RP neck-bridge combo. Then for a new middle pickup, I put in a G&L S-500 pickup, hidden under the cover from the old bridge pickup.
The S-500 was ~7mm taller than a Jaguar pickup, so I routed the middle pickup cavity by the difference.
I used a stepped drill bit (by hand) to open up the pole piece holes in the old Jag cover. The pole spacing was off by 1-2 mm, but once the holes are open enough to fit the larger poles, it is equally off to the stock pickups, whose pole pieces are also slightly off, so everything looks mostly normal.
The G&L is a neck/bridge model, polarity is South up. I wired a separate ground wire to the G&L's shield plate, in case I needed to swap the coil leads for phase, which I did in fact have to do once it was strung up (with roundwounds). Middle/bridge is also RW/RP.
Just to start, I set the Jag pickups to a normal factory height, then adjusted the G&L down until the volumes matched, which was considerably lower, which puts it out of the way.
First thoughts through my Tweed Princeton: It sounds big and full. If the Jag pickups in a Bass VI are a classic black and white movie, the G&L is in full color HD. They sound good together too, like some old Technicolor movie. Bridge position is much improved too, with the non-overwound pickup.
