This is the sustain block for a Floyd Rose Original bridge — the tungsten component that hangs below the base plate and anchors the tremolo springs. The block is 32mm and is designed as a direct replacement for the stock Original-series block. Tungsten is significantly denser and harder than brass, steel, or titanium. Greater mass means less string vibration bleeds into the springs and more stays in the bridge. Harder material resists the soft absorption that kills attack.

Before ordering, measure your spring cavity. The block length has to clear the body cavity in both directions of travel — too long and the block bottoms out before the bridge completes a dive; too short and the springs sit at the wrong pull angle. The mounting screw pattern also has to match your base plate exactly. A 32mm tungsten block in the wrong cavity or on the wrong base plate does not fit, regardless of what else it has going for it. Measure first.

This block fits the Floyd Rose Original series. Tungsten is a drop-in swap dimensionally for the standard Original block at 32mm — the cavity clearance question is about your guitar body, not the block-to-bridge interface.

If you are not certain this is the right block for your guitar, send us the make, model and year and we will check it against what we know.
