Dating an ibanez bass
An Ibanez serial number can tell you two things, year of manufacture and factory [or country] of manufacture.
There is no master list to correlate to a model number, these are consecutive serialized numbers only.
In 1974, the Artist-style neck joint; later in 1976 an Artist ´Les Paul´ arrives.
This sets the stage for the LP variant double cutaway Artist model in 1978.
In the 1960s Japanese guitar makers started to mainly copy American guitar designs and Ibanez branded copies of Gibson, Fender and Rickenbacker models started to appear.
Ibanez opens an office and warehouse outside of Philadelphia, Pennsylvania to maintain quality control on imported guitars in 1972.
1973: Ibanez´s Artist series acoustics and electrics are debuted.
If you're trying to figure out what model something is from the serial number, figure out what year it is then go to the catalog library for the corresponding year [or year before or after] to find the model.
Some models will never be found in the catalogs, that's just the way it is.
