Floyd Rose has begun production of the brass big block upgrades for their tremolo systems. These are similar to the big brass blocks that came on the earliest Floyd Roses and most would agree that those early Floyd  Rose's had a great tone to them. The large brass block is the reason why. As shown in the picture with the Floyd Rose logo on it, this is the real deal. A Floyd Rose made product for the Floyd Rose made tremolo. And look at the price!! This auction is for a 37mm brass big block for increased sustain and better tone. We also have listings for the 32mm and the 42mm big brass block depending on your needs.
