Well I finally bit the bullet and bought myself a FatBoy for this bass. If you didn't see my other thread, it turned out the bridge pickup was dead when I bought it in June. I'd been enjoying it with just the neck pickup working, and played a few gigs with the Who tribute band I'm with. Really good bass for that band! But I had to get it fully functional, and Mica and Mary got me a FatBoy. I first tried it in the bridge position and recorded a few things. Then, I swapped the pickups around with the AXY at the bridge and the FB at the neck. I like this setup much better. I think that pickup sounds better by the neck. I mean it is a genuinely good neck pickup. And the original neck AXY sounds GREAT in the bridge position (as it did at the neck). All in all, I'm very happy with this purchase! I never thought I'd be able to swing owning 2 Alembics at once, but I made it work.
Side note - there is a very prominent "848" in the neck pickup cavity. Wonder what that's all about?
