When I ordered my Series I in '81, part of the deal of the store which handled the sale becoming an Alembic dealer was that they had to stock two instruments in addition to the Series bass I was ordering. Alembic sent them an Electrum and a Distillate, both with maple tops. The Distillate was very, very nice. This was the first I had seen of an Electrum, but the literature they were passing out at NAMM that summer included a rather sexy shot of three distillate basses, including one in a marvelous cocobolo. It was stunning enough for me to order Series I in cocobolo as well. Sooo... Apparently there were at least three Distillate basses built long enough prior to the summer '81 NAMM show in Chicago to have made it into glossy loose brochure pages, fwiw..
