Mica,
Thank you for replying directly to my question. I've always heard that Alembic customer service is bar none, and I can see that rings true (even for 3rd or 4th owners!). You are absolutely correct that this bass has a much brighter tone than my other basses. I love a nice bright tone and that combined with the amazing Alembic electronics has made very happy. If I can't figure out the issues with the B string, I'll just use it as a thumb rest! Seriously though, I will look into your suggestions regarding favoring the neck pickup and checking the nut and bridge slots.
Bsee,
I've been thinking of trying Elixirs, so maybe I'll give them a shot.
Thanks,
Tom
