Serial numbers can be of some help in narrowing down the possible guitar models available for any given year, but the most accurate method of making the determination, particularly on a guitar where the serial number is not known, is by looking at the woods, hardware, and headstock, and then seeing what models from what year fit that criteria.
His two sons, Josef and Walter, joined their father's company in 19, and they successfully expanded Hfner's worldwide market, enabling them to survive the years of recovery following World War II.
Carvin's relationship with Hfner began in the mid-1960's, and would last until the late 1980's.
For example, there are some set-neck guitars (circa 1987) with the block logo (which wasn't "officially" introduced until 1988).
Because features and options were added or discontinued at various times during the year, and because Carvin would generally accommodate requests to use features that were no longer officially offered, there are some exceptions to the rules presented here.
For example, a TL60 made in 2002 has a serial number of 63663, while a Bolt made in 2000 has a serial number of 82398, and an LB70 made in 1998 has a serial number of 63094.
These examples are actual serial numbers, as well, and are only one example of the randomness of Carvin's serial number schema, especially from 1995 to the present.Click the picture to see the entire Hfner advertisement.Due to the amount of customization available on Carvin guitars, identifying the specific model can sometimes be difficult.For much more detailed information of features, models and the relevant model years, see the Guitar Identification Matrix.As with all Carvin guitars and basses, the presence (or absence) of a specific feature does not guarantee the year of manufacture.So, the best details to look at in narrowing down possible Carvin production years are logo style, neck, headstock shape, bridge, tuners and body construction.
