Ibanez Neck Woods & Cuts


One-piece and Three-piece Necks


The original JEM/UV (and RG, USA Custom ) necks are one piece maple.
The quartersawn maple strip (see cut diagrams) is one solid piece and
is joined just before the nut to the separate maple headstock. The cut
of wood is important, since the quartersawn maple provides a stronger
and more stable slab of maple which to construct the neck from.


Newer JEM (and Ibanez RG, J-Custom ) necks are three piece maple.
The dark bubinga strip (see arrow) is sandwiched between two
strips of maple. This creates a strong neck, while allowing for
various grades of wood to be used. The hard bubinga strip
helps eliminate the natural twisting or curling of wood

 


Scarf Joint: Attaching the Headstock


The original JEM and UV necks were one piece maple.
The scarf joint (arrow above) is where the maple headstock
attaches to to the neck just behind frets 1-3. The separate
headstock allows for a much stronger neck.


Newer JEM (and Ibanez RG) necks necks are three piece maple.
The scarf joint (arrow above) is where the maple headstock
attaches to to the neck just behind frets 1-3. The separate
headstock allows for a much stronger neck.


Some Ibanez guitars don't have the scarf joint, and instead have the volute (hump at the nut)
where the neck wood extends straight thru the headstock in a continuous piece.
The neck shown above is a 3-piece neck. The neck is 3 laminated pieces (2,3,4)
and the headstock shape is completed with the top and bottom pieces (1,5).


Approximate Neck Thickness Reference

A common source of question and confusion is "how does the size of this JEM neck compare to that JEM neck". If you've read Jemsite.com, you will know that JEM (and most Ibanez) necks are hand finished which will provide some variability in the final neck size and proportions. Making matters more confusing is the fact that the "JEM" neck has changed and evolved over time according to Steve Vai's demands, since it's a signature model guitar. It has gotten smaller and more "Wizard-like" compared to the original 777 necks from 1987
