Floyd Rose 7-String Fat Brass Block: More Sustain, More Tone

The Floyd Rose FR17FTB37 1000 Series Special 7-String Fat Brass Tremolo Block (37 mm) is designed to increase sustain, resonance, and tonal richness on your 7-string Floyd Rose-equipped guitar. Favored by guitarists who want more mass at the bridge for a fuller, more musical sound, this genuine upgrade part delivers a practical improvement in both feel and performance due to its 37 mm size and pure brass material.

Notable Functional Benefits

Brass has long been a top choice for luthiers seeking extra warmth and clarity. Thanks to the "fat" thickness of this block, you don't just get more sustain—chords and single notes become more defined, with the midrange really coming to life. In some cases, the larger size may require routing for floating bridges, which demonstrates its commitment to serious tone enhancement.
