Subtract one from the other and I'll have a rough-cut figure for how many were made. PRII owners were kind enough to start sending their serial numbers in.
I was puzzled to see how some of them were separated by over 100,000.

Hit the jump to see just how old that guitar or bass really is. Most notably, production dates have been penciled or stamped on the butt end of the heel of the neck of most guitars and basses, although there were periods when this was not consistently done (1973 to 1981, for example) or simply omitted.
All green board and all cream board Blues Juniors are identical electronically, despite what the salesman told you. Below is a table of revision dates and the changes made on those dates. Fender adopted a two-letter dating code in 1990, and the code can be found on the Quality Assurance label, inside the cabinet, sometimes located on the bottom, next to the reverb tank, sometimes on the side.
The codes are usually handwritten, and the letters can occasionally be hard to decipher. There is no reliable way to date 2003-2005 amps other than to ask Fender customer support to look up the date from the serial number, although you may find a date code on the speaker.
While there have been periods of dramatic change—such as the transition periods between the Leo Fender years and the CBS years or the transition between the CBS years and the current ownership—most models are generally feature-specific and do not change from year to year.
Given the modular nature of Fender production techniques, an individual neck may have been produced in a given year, then stored for a period of time before being paired with a body to create a complete guitar, perhaps, for example, in the following year.Therefore, while helpful in determining a of production dates, a neck date is obviously not a precisely definitive reference.Most specifications for a given Fender instrument model change little (if at all) throughout the lifetime of the model.The cream-colored board is laid out entirely differently (and better) than the green board. But the old ones sound darker, while the new ones are brighter, with more emphasis on treble tones.One is not necessarily better than the other; the dark tones are nice for blues and jazz, while the new amps do brighter tones better.
