I'm writing in to provide some additional specs that are not included in the description:
The string spacing is 1 3/8", like the Les Paul version. The nut itself has a radius, which is relevant for installing in a nut slot. The radius is 7.25". The range of height adjustment depends on the way you install it. If the nut is sitting at the bottom of the slot, then you only have about 1mm of adjustment available, and the lowest setting would be 2mm off of the fretboard. I believe this is the wrong way to install the nut; your nut slot would have to be 2mm or less to install the nut this way. There is a tab that extends onto the fretboard towards the headstock; if you install this nut so that it rests on the fretboard, and your nut slot is 5mm or more deep, then you have a range of about 1 to 3mm above the fretboard, on a 7.25 radius fretboard. In the worst case scenario (a completely flat neck), then your range on the outer strings will be the same, but the range on the middle strings will be about 2 to 4mm above the fretboard. There are about 24 increments available in the 2mm adjustment range (12 useable on a flat neck). To me, what this amounts to is that if you have a flatter neck, and you want low action, this might not work for you (1mm is decently low, but 2mm? Not really very low)
