I have a '68 EB-2 that lives at my friend's studio in Massachusetts. Although many don't love the "mudbucker" I do. However, this one is messed up - the E A & D strings are fine but he G string is much lower in volume. The weird thing is that when you engage the "baritone" switch that cuts the lows, then the A D & G are good and the low E becomes much lower in volume.
The other day Curtis Novak was clearing out some EB shaped pickups that were set up like Guild Bi-Sonics. I wasn't fast enough and didn't get in on the deal. However, it made me realize that I would actually like to Alembicize this bass as well. On the Alembic website it says that the Gibson humbucker shape was available as an option, but I don't recall ever seeing any. I wonder if there are any floating around?
Here's a picture of the bass:

This isn't a high priority for me, but just thought I'd put it out there.
