Floyd RoseOriginal Fat Brass L Tremolo Sustain Block - 42mm
Independent shopping perspective
The Korena take
Built around unused space beneath the tremolo arm, this 42mm L-shaped brass block adds mass beyond a conventional sustain block. The result is positioned around longer sustain, added brass character, stronger chord definition, fuller individual notes, and more midrange resonance. Its larger profile also changes the bridge’s available upward movement, and it can be set against the body when configuring the bridge as blocked.
Strong match
Who this is for
- Players seeking added mass, sustain, and midrange resonance from a Floyd Rose tremolo block.
- Blocked-bridge configurations where the sustain block is set to rest against the guitar body.
Consider the trade-offs
When to look elsewhere
- Setups that require unrestricted upward tremolo travel.
- Floating-bridge installations without room for any needed spring-cavity routing.
