BASS SET THROUGH NECK
A set-through neck is sort of a mix between a set (glued) neck and
neck through neck. On a set through instrument, the neck extends into the body allowing the string vibration
to run unaltered from the nut to the bridge.
This solution allows to build the body in a single piece of wood as opposite
to neck through construction where the body is made of two separate pieces, glued at the side of the neck.
Despite this fact this solution offers some advantages, it is still not so diffused as it would deserve even if it used by some manufacturers
with success on both side of the ocean especially on basses.
