Floyd Rose RG-FTB Brass Fat Tremolo Blocks will add sustain and mass to your Floyd Rose bridge. Brass has great tonal capabilities that add another great aspect to this replacement Tremolo Block. This block also allows you to customize the sound a bit. The larger size of this block means that it can limit the upward travel of the tremolo. Another configuration is a blocked bridge that would rest the block against the body. If you were to go for a floating bridge you would likely have to do some routing in the spring cavity. The dimensions are 50.15mm width and 12.9mm thickness.
