Stone Tone Tremolo Sustain Block

The Stone Tone Tremolo Sustain Block is precision-crafted from natural Volcano Black Absolute Granite, engineered to maximize tone, clarity, and sustain across your instrument's full frequency spectrum. Natural granite features an optimal crystalline atomic structure and dense composition, dramatically enhancing acoustic transfer and reducing signal loss from the guitar to the amplifier by up to 30% without requiring synthetic processing.
Designed as a substantial upgrade over standard metal blocks, this unit can function in floating configurations or be set flush against the guitar body for a solid blocked bridge setup. Its robust mass and density naturally improve note definition, warmth, and overall acoustic resonance across clean and high-gain playing styles alike.
Compatible with Original Series 6 and 7-string, Special Series, and 1000 Series Pro tremolo systems, each block includes durable stainless steel mounting screws and a dedicated 0.020-inch copper grounding strip to ensure optimal electrical shielding and buzz-free performance.
