I worked on a Fernandez with the Sustainer thing on it a couple of years ago. The pickups were average, not horrible but nothing to write home about either.
The Sustainer caused a feedback loop that allowed a single note to feedback and sustain for quite awhile. It was fun for a minute but it wasn't all that cool. A good tube amp opened up does the same thing.
The guitar was well enough put together and played nicely.
