Kim Breedlove designed the Auditorium body shape in 2005 for a sound that falls between the intimacy of the best-selling Concert and the deeply resonant power of the Jumbo. An extremely responsive and versatile shape, the Auditorium’s depth and lower bout produce the articulation of the Concert with tonal depth reminiscent of the larger-bodied Jumbo. When played acoustically, this shape has the volume and projection to fill a room, plus added clarity, balance and sustain due to the magical combination of the larger body with the Breedlove Bridge Truss and a thinner graduated top. The Bridge Truss allows the top to move more freely, so melodies and fingerpicking won’t get lost. And when you really want to dig in and strum, these guitars can take it, projecting your music to the audience in the fullest, most expressive way possible.
European spruce, picea abies, originates in Germany and Italy, though it is usually from the Dolomites in Italy. European spruce is often thought of as the ultimate wood for classical guitars because of its light weight and stiffness, coupled with its very pale, even coloration. The tone profile provides a sound rich in overtones, focused, full of nuance and tone color – a sound often preferred by fingerpickers. It offers a quicker response and greater headroom than Engelmann, and usually takes a slightly longer period of playing time to open up than Engelmann or Sitka. The coloration is even, pale and very light in color.
Back and Side Wood
Madagascar rosewood, dalbergia baroronii, originates in Madagascar, an island in the western Indian Ocean. Madagascar rosewood is a beautiful wood, visually and tonally, and is often thought of as an ideal substitute for Brazilian. It delivers crisp, bold tones, good sustain, and a great bass response, with an equally dynamic high-end not found in East Indian rosewood. It is known for a dark and bell-like overtone with a slow response. Coloration ranges from a light yellowish brown to a darker orange or reddish brown. Darker black streaks are common, and can produce a grain figure. It can exhibit wild landscape-like figuration, often compared to spider webbing, much like Brazilian rosewood and ziricote.
Breedlove graduated tops contribute stunning balance from lows to highs. How? Graduated tops are slightly thicker on the treble side, balancing the higher energy treble frequencies with the lower energy bass frequencies traveling through the thinner bass side. The result: clearer, cleaner highs and stable, resonant lows. Because no two soundboards are exactly the same, Breedlove craftsmen evaluate each top for stiffness and density, and then graduate it accordingly. The amount of graduation is customized for each individual instrument. The top is sanded to the precise graduated thickness to achieve optimal flexibility and stiffness. This hands-on process is one of the major contributors to the Breedlove sound.
Breedlove Bridge Truss
The Breedlove Bridge Truss (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.
Breedlove guitar necks feature a slimmer neck profile, which enables comfortable play, even with smaller hands. Unlike traditional dovetail neck joints that require major surgery for a neck re-set, it is easy to adjust the play action and neck angle with the Breedlove bolt-on neck and single-action truss rod. The hand-rubbed, semi-gloss Breedlove neck finish contributes to ideal playability – the finish process alone takes three days, including precise finish coat applications, fine sanding, and hand buffing and rubbing.
