Floyd Rose Stone Tone Sustain Block 42 mm — Upgrade for Floyd Rose Tremolos

The Floyd Rose FROSTB42 Stone Tone Sustain Block 42 mm is a replacement part designed to elevate the performance of tremolo-equipped guitars. With granite construction, it appeals to players seeking increased sustain and clearer tone, while also reducing signal loss. Using a dense natural stone, this instrument component changes the feel and response of your bridge.

Unique Materials and Acoustic Benefits

Distinguishing this sustain block is the use of Volcano Black Absolute Granite, ranked as the fourth densest material on the planet. A crystalline atomic structure enables excellent sound transfer, separating this option from brass or steel alternatives and delivering dramatic improvements in note separation and sustain.

Key Functional Features for Tremolo Performance

Stone Tone blocks offer practical advantages for both tone and reliability. The 42 mm height is designed for direct fitment in many Floyd Rose bridges, and mounting screws in stainless steel are provided for secure installation. High-density granite means not only longer sustain but also at least 30% reduction in unwanted signal loss between your instrument and amplifier.
