The ESP Guitar Company

I just purchased a supposedly 1 of 100 ESP Horizon-I. What makes this "special" is that it is made in the Kiso Custom Shop but it has a single coil Sustainer in the neck position and a factory EMG 81 in the bridge. I can barely find ANYTHING on this other than it was a Japanese only and that there were 2 versions (I have the newer version 2). Has anyone else heard of this? Do I have something special or no? Thanks in advance!
