Here is some info on the ANJ neck joint.
The first two drill holes at the bottom of the neck are 1cm from the end and the sides.
The third drill hole which is out of line, is 4 cm from the end and 1.5cm from the edge.
The fourth drill hole is 6cm from the end and 1cm from the edge.
Another tip for construction is that on the Jem BSB, the nut is not mounted on the neck but on the fret board.
I would be interested to know what type of wood the fret board is made of!!!!!!!! (As in type of rosewood).
