Floyd Rose FROTuB32 Tungsten Sustain Block 32 mm – Maximize Your Guitar's Sustain

This 32 mm tungsten sustain block is engineered for tremolo users who want more sustain and clarity from every note. The FROTuB32 is designed to fit Original, Special, and 1000 Series 6- and 7-string bridges without modification. By replacing a standard block with tungsten, you add mass to the bridge, keeping more vibration in the bridge and less in the springs—this leads to a brighter, livelier tone.

Why Tungsten Sets the Standard for Sustain Blocks

With a density over four times that of titanium and more than twice that of brass, tungsten offers superior hardness as well. As a result, the FROTuB32 efficiently transfers string vibrations while resisting the sound-dampening effects found in softer metals. Many players notice an immediate and clear improvement in both sustain and note definition after installation.
