I asked about several of their nuts, and the scale length is not so much of an issue according to them. Considering that there is around a 1.5 mm difference between the standard nut and the Earvana compensation, that difference over 24.75 to 27 inches doesn't work out to be that much. At least that is what their reply implied. I got one for my Les Paul and it worked dandy. A friend cracked off the corner, so I am waiting for another. This leads my complaint with the system is that the edges are still sharp, and for no reason. They can catch on things when they could be a little less sharp, hah the pun. Anyways, The other problem is that it is for a 12" radius neck so a little fin-agle-ing has to be done if you want it to look perfect.
