here more info i got from a guy in the fender forum
What we have here is an example of an original American Standard Strat that by this time, had received a few minor updates since their debut in 1987/1988. Compared to earliest models, this version features:
* Fender's "spaghetti" logo vs. the old silver transition-style logo.
* Fender's Delta Tone system: the bridge pick up is slightly hotter and the no-load tone control took the place of the old TBX circuit. The American Standard pickups have remained the same until 2000 when the line was renamed "American Series". The pickups were essentially the same except that they were now staggered instead of flat. These pickups have only recently been supplanted by Fender's Custom Shop Fat 50's.
Actually; since your Strat is a '99 model, it may be transition model between the "Standard" and "Series" change. If that is the case, your guitar may have the H-S-H pickup routing vs. the universal (aka; "swimming pool" route) and have body contours that more closely match the original Stratocaster body. The headstock still has two string trees and does not have staggered tuners.
The original 2-point American Standard differs from the current production unit in that it uses so-called block saddles with an off-set screw vs the vintage style bent-steel saddles with a center screw. The current American Deluxe tremolo is a variant of the original American Standard.
