I KNOW THIS GUY! He was a fellow Fender man at the Blue Bear School of Music circa 1972-73 at the old Ocean Ave. location. When I first arrived, a whole slew of bass players had modified their J Basses with Alembic stuff, though I couldn't tell you what, exactly, except they all had millions of knobs and a really thick, rich sound.
I ran into Jerry at a NAMM show a few years back and he told me he's teaching, among other things.
I remember him as a great guy! Those were magical times, with Chris, Kevin and Bonnie Hayes; Mark Needham (producer for several industry giants), etc.
