Floyd Rose Tungsten Tremolo Sustain Block – StewMac

Floyd Rose Tungsten Tremolo Sustain Block

Get more sustain from you Floyd! Super dense tungsten gives your guitar greater sustain and resonance—and it’s a drop in upgrade.

When it comes to sustain, the most important properties for metals are density and hardness. Tungsten is over four times denser than titanium and more than twice as dense as brass.

Most standard tremolo spring cavities simply aren’t large enough to accommodate bulky sustain blocks. These blocks offer the highest density available in a block that conforms to the original size specifications of your Floyd Rose bridge. This is a direct replacement for the stock Floyd Rose sustain block, adding up to a half pound of mass to your bridge.

High density for better tone
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 and a great deal of resonance is lost. 

A high density sustain block means greater mass and more vibration transmitted to the bridge where it belongs. With this tungsten sustain block, every note will be brighter with a noticeable increase in clarity and sustain.

Drop in upgrade
This block is the same width as the standard Floyd Rose sustain block. Center to center hole spacing of the outside screws is 1.345″ (34mm). Simply pick the model that matches your bridge.

Want even more mass? The Fat Tungsten version has even more bulk for extra sustain. 

Choose your block depth:
42mm: for flush-mount installations (the Original)
37mm: for recessed bridges
32mm: for deeply recessed bridges and Floyd Rose Pro

These blocks will fit the Original Series 6 and 7-string, and the Special Series and 1000 Series 6-string. These blocks will NOT function on the 1000 Series Pro 7-String or Special 7-String Tremolo Systems.
