thats not stictly true,
the first is a rocker joint, used to make getting the neck angle right more easy, its a **** way of making a contact between the neck and body,
the second and 3rd are in truth almost identical, as they are flat joints which have great body to neck contact, the extra 2cm length makes no tonal difference, it just copying a 59 to better spec...
old tokais use the 2nd joint , newer high end use the 3rd,
but, in my opinion, there is no good reason for any tonal supremicy of 3 over 2, the extra wood is so little, it would be superseeded by things like solid tailpiece connections or locking bridge, which at theat level of minutae are equally important..
in summery 1 is a cheap way of making a neck angle easily and a real tonal compromise as there is very little neck to body contact,
2 and 3 in my view are both great neck joints...
