I bought these (individually) off eBaY (before I actually bought the Custom lol). The first time that I installed them, NOTHING worked. I paniced (I needed it for an audition the next day) and put the original pickups back in (it worked fine all of a sudden hahaha). Later , I installed a new Mojo wiring harness that I bought from an online pal. It worked fine. Last night the gf was gone, so I decided to try again. This time the bridge pickup (double cream bobbins) worked, the neck didn't. I resoldered three times, but it seems like the pot is bad... good thing I still have those old pots, eh? I soldered the neck pu straight to the switch wire, it worked (temporarily) so I know that the pickup itself works. The good news is that the bridge 'bucker is a screamer, it sounded almost like a P90 Junior last night, which ain't a bad thing. I doubt if I'll work on it tonight, I don't have a dedicated workbench, nor real good light to work with. First, I'll look at the pot, make sure the ground wire is still attached. But if I HAVE to, I'll put one of the old pots back in... The old pickups, Shaws, according to the gurus on the LPF, weren't bad. Same way I fet about the Classic 57s on my historic... "not bad". But the Antiquities... mmmm....!
