I have an FR1000 that's in the new JS75 and I need a new block for it as it needs a 37 or 42mm. Getting one for the 1000 series here is impossible, so I'll probably have to get one for the German made model.
Will they fit before I go and outlay the cash?
I just had to buy a 1000 for my lp, and during my conversation with Floyd rose they did tell me that the 1000 series is identical to the OFR save for location of manufacturing. So I would say based on what they told me it would be, but I have never tried swapping them.
