les pickguard en ABS des premiers modeles (54-59) restent blancs comme au premier jour.... l'usage des thermodurcissables ne commence pas avant 57, non? Me trompé-je? *^_^*
houla ! on commence serieusement à rentrer dans le detail.
ce que je sais, c'est que les strats 1ere generation (54/59) ont un pickguard qui ne change pas de couleur (si on ne la range pas dans sa cave à coté des buches et des pommes de terre) contrairement aux pickguard 3 plis de la generation suivante.
sinon pour une reference technique serieuse, je crois qu'on peut se baser la-dessus :
Pickguard Material
Black pickguards: black pickguards were used from 1950 to mid-1954 on the Telecaster, Esquire and Precision bass. This material consisted of a fiberous bakelite, and was about .060 (inches) thick. The fiberous material was added to the bakelite to add strength (bakelite is too brittle and would crack at that thickness without it). Finally the black pickguards were clear-coated with clear nitrocellulose lacquer (top side only) to give them depth and shine.
White pickguards (single layer): starting in mid-1954 on the Telecaster/Esquire and Precision bass, and from the start on Strats in 1954. Fender used a single layer white pickguard material made from ABS or vinyl about .060 (inches) thick. This relatively new material for the time was cheap, easy to work with, and somewhat flexible. Note bakelite was never used for white Fender pickguards on any model (though many people refer to white pickguards as such; but it's not bakelite). Fender stopped using the white material in mid-1959 except on the Telecaster, Esquire and DuoSonic/MusicMaster. In this case the single layer thickness increased to .080 (inches), and was used till about 1965 (Esquires till about 1967, when all old stock was depleted).
Multi-layer pickguards: starting in mid-1959 Fender switched to a 3 layer pickguard (w/b/w) made from Celluloid on most models. The Pbass and Jazzmaster used a 4 layer pickguard of Tortoise/w/b/w (except on certain custom colors which used a 3 layer w/b/w pickguard). These celluloid 'guards had an outer white layer with a mint green/yellow tint, thus giving them the name "green 'guard". The amount of green/yellow depends on the abuse and UV the pickguard was subject to. To some degree the effect is not only caused by age and sun, but the "felting" of the black layer below the white layer. This material was used till January 1965 when Fender switched to vinyl or ABS for their multilayer pickguards (Celluloid was dangerous and very flamable, and shrunk with time causing cracks). Sometimes these pickguards are called "nitrate 'guards" because nitric acid is one of the key ingredients used to make celluloid. The 1965 and later white pickguards do yellow a bit with age. But even aged white 'guards look much different than the older "green" 'guards. In the late 1960s, white Stratocaster pickguards change slightly (not sure about other models). Though from the front they look identical to the 1965 to 1967 variety, the 1968/1969 white Strat pickguards had a bottom layer (the layer not seen unless the pickguard is removed from the body) of "pearloid".
