Floyd Rose FRP1FTB37: Fat Brass Block for Enhanced Sustain

Players seeking better sustain and tonal clarity often choose the Floyd Rose FRP1FTB37 1000 Series Pro Fat Brass Tremolo Block 37 mm as a direct-fit brass replacement for their 1000 Series Pro tremolo systems. By adding mass to the bridge, this model brings increased resonance and a more focused, warmer sound. Many guitarists notice a fuller midrange response, particularly compared to standard blocks. The FRP1FTB37 offers an easy upgrade path for those wanting better vibrato performance without complicated modifications.

Brass Construction with Noticeable Tonal Impact

Its solid brass construction is highly regarded by luthiers because it adds warmth and clarity at once. The extra mass of this "fat" block is known to boost resonance and sustain, especially in the midrange, delivering a livelier feel under your fingers. That classic, vintage-inspired sound character is what many players value for both rhythm and lead work.

Functional Fit and Practical Specs

Fit and compatibility matter when upgrading a tremolo, and this block is specifically sized for 1000 Series Pro (6- and 7-string) Floyd Rose systems. Dimensions include:

• Height: 37 mm — compatible with most 1000 Series Pro bridges
• Width: 50.15 mm — fills the cavity to add mass
• Its thickness is 12.9 mm, giving you more sustain without unnecessary extra weight.

The extra size might require slight cavity routing for a free-floating bridge, but it generally fits most standard mounts directly.
