You are correct Jazzywee, but that groove IMO is counter productive for that purpose. I have 2 JDs, one is like this in the picture, called Series 2, the other one is Series 3, slightly different body shape.
Influence? Yes for sure, although John Diggins claims he had never seen an Alembic when in late '70s came up with this bass. The electronic looks kind of sophisticated but in reality is not that powerful, again IMO, light-years from an Alembic Series, but the price of a new one reflects it.
I'm going to keep one and sell the other, for that nostalgia of those early L42 years
