Well I'm on the fence here about the belly cut. Here's a quick thing I did in paint. Altered the neck heel to be closer to what I did as to get a better image. What do you guys think? Red? White? Fernando, I'll get a pic of the whole guitar from the front in just a few mins.... The back isn't done yet so no pics, lol.
And about the Kahler, three things to consider that I didn't mention. One, the stud spacing and the route is not the same as any Floyd, so unless it's a new build, I wouldn't recommend it. See how the pic of Paul Gilbert's guitar has an adapter plate where the old trem was?
Two, the range of downward motion is more limited than a Floyd because of how the studs and the pockets on the trem interact. All this means is that you can't make your strings totally loose spaghetti like Eddie Van Halen. The pull-ups aren't affected they have about the same range, but going down is. It's absolutely fine for any whammy trick except for making your strings have no tension.
Three, it is not easy to find parts and the ones that are available cost a fortune. Whammi World sells, for instance, one of the saddle assemblies for $35
Other than those three things, yeah, I do feel it is better than the Floyd Rose. It looks better(IMO), it feels better(IMO), it's more adjustable, it's lower and the knife edge is easier and cheaper to maintain.
If you like Strat style guitars, look for a used Peavey Vandenberg or Nitro. They used the Killer and generally it is cheaper to buy a whole used Vandenberg than to buy one of these trems outright.
