I've owned my Series I since 1997. It was a gift from my family when I graduated from high school. I was then and still am a dedicated bassist, so owning a Series Alembic is a real joy. I was curious about what information might be turned up for my model (serial # 76 573). It's a small body Series I with unusual Grover twisted tuners. Before I purchased it, the previous owner had installed a master volume. I've played live with it numerous times. the neck position Q is a little wonky, but I finagle it :-)
