You could consider the FRT-2 the very first “licensed” Floyd Rose ever, although a licensed Floyd didn’t technically exist at this time. The FRT-2 was released at the same time as the FRT-1 in 1982 and first appeared in the 1982 Fernandes catalog with its brother, the FRT-1. It was produced alongside the FRT-1 and supposedly possesses the same high quality, but it had chrome-plated brass saddles, which was likely a cost-saving measure. The FRT-2 does not have insert blocks or locks at the saddles like the FRT-1. It’s a string-through model, and this is the primary difference.
The FRT-2 was put on Fernandes ST guitars which were a step below the highest grade versions (but still high quality). That being said, the FRT-2 did not die out after six months like the FRT-1. In fact, the FRT-2 lasted all the way until the end of the Japanese Floyd Rose contract in 1985.
