Used to call these 'East-Meets-West' electronics. Maybe that's an Alembic colloquialism? (I could swear it's on my build sheet...) The description is more descriptive of function though. I honestly wouldn't know what it meant if I didn't hang around here.
It's a beautiful bass, and a shame they have to sell for unfortunate reasons. Is it just me, or are the horn points a bit more curled than usual?
