Remember one of the guitars in
Steve Vai's collection that has a split
Floyd Rose-type tremolo that let him whammy the bass and treble strings separately? Looks like somebody's made a
commercial product out of the concept!
Check out the installation page... they have a version that fits recessed Floyd-type routing, and they include a graphite replacement nut that fits the Floyd nut mount as well. Also check out the stabilizer in the back... looks a LOT like the one we saw in the ZeroRocker pics.
