Hello Bill, welcome to the Club! This community is one happy, friendly and very international patchwork quilt of Alembic fanatics. You'll soon find out that it gives you a warm feeling of coming home every time you come by for a visit.
I can't be very helpful about the Electrum electronics I'm afraid, others undoubtably can and will, but a stand-by switch is indeed an option Alembic offers, my EVH has one (with indicator LED). If it's a genuine Alembic addition to your instrument it allows you to keep the instrument plugged in without draining the batteries. Not to be mistaken with the stand-by position on a 4-way pickup selector switch, because that does drain the battery.
Feel free & somewhat obliged to post pictures, at least in the Showcase section of this wonderful club. But we certainly don't mind if you also post them in this thread. I'm sure our 6-string brothers are delighted to see another non-bassist joining this club that's still dominated by the low end. For me personally Alembic is responsible for me selling all my guitars and becoming a new born bassplayer. So beware!
