It's a 2700/2710 Killer.
It's pretty cool and just drops straight into a 2 point strat cavity.
It has adjustable radius & string spacing and also individual string height!
Unfortunately the mounting studs/knife edge kinda things didn't come at the same time but hopefully they shouldn't be too long.
In theory I could just use a countersunk head machine screw as a temporary fix but i'll just wait. I love the fact that it has no knife edges to wear out and the replacement stud pieces that it pivots on are $4 each.
