So cool... 

I have often wondered if John McVie's Penguin & Porpoise bass had a variation on, or maybe even a predecessor to one of these Modulus BassStar necks. (that mysterious dark Standard Point body with a Fender-shaped graphite neck and crazy Series electronics) Could just be a wacky coincidence, but one wonders, who else was making graphite necks and working closely enough with Alembic in the mid/late 70's to be involved in the project?
