Our exclusive tungsten sustain blocks for Floyd Rose tremolo bridges offer the highest density available in a block that conforms to the original size specifications of your Floyd Rose bridge. When it comes to sustain, the single most important property of a metal is density followed by hardness. Tungsten is over 4?átimes denser than titanium and more than twice as dense as brass. To equal the mass of our tungsten sustain block, you would need a titanium block 4 times the size and a brass block double the dimensions of our tungsten block.
Most standard tremolo spring cavities simply aren't large enough to accommodate?ábulky sustain blocks sold by other companies. Ours is a direct replacement for the stock sustain block adding up to a half pound of mass to your bridge.
Why are density and mass important to sound and sustain? A fixed guitar bridge efficiently transmits string vibration from the bridge to the body through a large contact area but tremolo bridges are limited by a few very small attachment points. A great deal of resonance is lost to the bridge through the tremolo springs because the springs absorb and dissipate vibration very well. This is one of the reasons expensive studio microphones are suspended by springs to isolate external vibrations. A high density sustain block means greater mass which means less string vibration transmitted to the springs and more in the bridge where it belongs.
Soft metals absorb sound and cancel sustain. Tungsten is much harder than steel and titanium and over twice as hard as brass. No other sustain block offers the perfect combination of mass and hardness.
With our tungsten sustain block, every note will be brighter with a noticeable increase in clarity and sustain.
Same thickness as the standard Floyd Rose sustain block.?á?áCenter to center hole spacing of the outside screws is 1.345" / 34 mm.
These blocks will fit the Original Series 6 & 7-string, and the?áSpecial Series & 1000 Series 6-string.?áThe Special & 1000 Series 7-String Tremolo Systems have a sustain block mounting hole spacing which is unlike any of our other systems-- please see the?á1000 Series / Special 7-string Fat Brass Tremolo Block?áfor those bridges.
