yeah i thought they were dis-continued years ago but i just saw one on a new guitar.
they look to be a high quality bridge. my guitar teacher had one on an old beat up guitar, maybe a jackson, the axe looked like a 1980's shred surviver. so did the teacher, oddly he didn't know much metal.
back to the point. it has rollers on the saddles so you stay in tune, fine tuners so you can use a locking nut and again stay in tune. no annoying string locks to slow down string changes. infact the strings are top loaded, very easy.
they pivot in the center if i remember right. probably not good for dive bombs. overall looks like a good bridge system. i'd try one if i found one.
