Laminate Constriction

[Greg Lorisco]

I’m new to KS basses and was noticing a difference in KS from other neck-through (NT) basses. Most NT the neck gets thicker where it joins the body and is the same thickness as the body. But on some KS the neck stay the same thickness and there is another piece of wood that is laminated on top of it to match the thickness of the body.

What is the reason for this type of design and how does that affect the tone?
