#19 Llevas razón en que ahora es Coreano, no chino. No llevas razón sin embargo en que los materiales iguales en ambas series, puedes consultar el enlace que adjunto. Y hay tanto zinc como latón. De todas formas copio directamente:
Floyd Rose Original: This original unit was featured on overseas Focus guitars around 984-1987 and was used on American Kramer's as an option on all guitars after 1983. This is probably the most famous of all the Floyds in that it was used on Edward Van Halen's 5150 and Frankenstrat. Chrome tend to be the most durable of these Floyds when it comes to rust and pitting. Note: Most Kramers utilize the screw in trem arm on their Floyds, not the "collared" trem bar seen on the newer Floyds.
The Original Floyd Rose features the hardened steel fulcrum points.
O el de siete cuerdas: The Floyd Rose 7 String - German
The 7 String unit was constructed with the ultra-shredder in mind. It features everything found in the Original Floyd Rose 6 String version, and is constructed in Germany to original
specifications for steel hardness.
El Coreano o FRT1000 series The Floyd Rose OEM - Korean
The OEM Floyd unit is near identical to the Floyd Rose Special, but is only found on guitars that are sold with the units installed. These are not sold for purchase individually unless in special circumstances. I
t features zinc alloy saddles in place of steel and a zinc alloy sustain block in place of brass.
Y por ultimo el Special: The Floyd Rose Special - Korean
The Floyd Rose Special is an Authentic version of a licensed Floyd Rose tremolo system manufactured in Korea exclusively for Floyd Rose. The Floyd Rose Special maintains the construction parameters and features of an Original Floyd Rose,
while utilizing zinc alloy saddles in place of steel and a zinc alloy sustain block in place of brass. The design specifications and high quality materials of the Special Series Floyd Rose bridge will hold up to the demands of today's performers.
"Zinc alloy sustain block"....
Que cuando escribo lo hago con conocimiento de causa...
PD: Aunque es extraño que en la página oficial de Floyd Rose ponga a los Coreanos OEM de las 1000 series como una copia idéntica en materiales y diseño del original alemán y sin embargo en vintagekramer ponga que no son los mismos materiales. O ha habido un cambio por parte de Floyd Rose últimamente y ha decidido meter los mismos materiales que los del puente original y en Vintagekramer están confundidos o quizá es que en su día los 1000 series eran de los materiales citados y ahora son exactamente igual que los originales alemanes.
