Ibanez Neck Specifications

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
