Breedlove Bridge Truss
Select models feature the Breedlove Bridge Truss – most commonly the Concert and Auditorium shapes. The BBT reduces tension on the soundboard of the guitar, so the top wood is able to vibrate more freely, producing remarkable sustain, balance, and clarity. The BBT also allows for a thinner graduated top, thereby allowing Breedlove craftsmen to bring out the optimal sound from the top wood without sacrificing structural stability. Relieving much of the string tension from the bridge prevents “bridge belly,” ensuring top stability for decades.
Guitar strings can exert up to 230 pounds of pull from the nut to the bridge. Traditional methods for preventing top bowing at the bridge usually involve heavy internal bracing and thicker tops. The BBT compensates for this pressure in an innovative way: The BBT is mounted to the bridge from the inside and is connected into the tail block of the guitar, pulling downward on the underside of the bridge to distribute some of the tension, relieving pressure on the top. The resulting tonal effect on BBT-equipped guitars is more resonance and livelier sound with enhanced overtones.
