The name as used in various catalogs, also known as the model number (more basic information about model numbers on that page). The finish code is not included but has its own field (see Colors). Also in Mahogany Oil.
The years indicate the period this guitar was made and/or released. To find out how long a certain guitar model was produced, you can ether look at the serial numbers of various copies of that guitar or you can look at Ibanez parts lists. To find out when a model was released, you can also use normal catalogs. These two don't always come to the same thing. Guitar models do not always appear in the annual catalogs Ibanez releases every January, for instance when a model is only released for a very short time. In some cases, production starts a little bit earlier: when a guitar has to be in the shops by January, it might already by produced in November of the foregoing year. Also note that in some cases, guitar models are released only in certain areas in a certain period.
The areas in which this model is released. For now, we discern EU (European Union), JP (Japan) and US (United States). This is also the division Ibanez uses for its catalogs.
The land in which the guitar was made.
The material or materials used for the body, usually a wood species. If a guitar has a top from a different kind of species, it is also noted here.
The material or materials used for the neck, not including the fingerboard, usually a wood species. For many 'modern' Ibanez guitar, a laminate of multiple species is used, for instance 5-Piece Maple/Walnut means that the neck is made of three pieces of maple with two pieces of walnut in between. If the headstock of the guitar is made of/contains a separate part of wood, this doesn't count as a 'piece'.
The material used for the fingerboard.
The colors of the finishes available. Each color has its own name and abbreviation. Note that some finishes are available for a limited time only.
The color of the hardware, usually the bridge, machine heads and knobs.
The type of inlays used in the fingerboard.
The color/material of the pickguard, if the guitar has one.
The way the neck is set to the body. The three main possibilities are set-in, neck-thru or bolt-on. Set-in means that the neck is glued to the body. Neck-thru means that the neck wood runs through the whole body. In that case the body usually consists of two 'wings' that are glued to the neck wood. Bolt-on means that the neck is attached to the body using bolts. In the last case it is sometimes specified how the heel of the body is trimmed. This could be as a Cutaway Heel or All Access Neck Joint (AANJ).
The shape of the neck, usually the name Ibanez has made up for it. Common names are 'Wizard' or 'Ultra'.
The bridge used on the guitar, so basically the device used to attach the strings to the body. This can also be a tremolo or a bridge and tailpiece combination.
The number and type of frets.
