I've had this bass since 2003. I'm a member on the Alembic site forum where there are several posts on this bass in the showcase section under series one basses.I acquired this one from Michael Delacerda (Alembic forum)who at the time had quite a few old ones, and was willing to part with it for a very reasonable amount at the time.The two nubs between the knobs are actually the hum-canceling controls. All you need is a screwdriver to turn them. The battery compartment is under the brass plate between the pickups.I spoke to Rick Turner about this bass and he remembers it being in the shop the same time John McVie's bass was being built.
