Tacoma Guitar braces are triangular in shape because they have equal strength to a rounded brace with less mass.
Lower mass allows the top to vibrate more freely, and increases the guitars response.
A Luthier's rule of thumb is that low, wide braces are best for bass frequencies, and tall, thin braces are best for treble frequencies. Tacoma has applied this thinking to their bridge and it works. The solid Maple bridge plate is asymmetrical, and placed diagonally to enhance the dispersion patterns of the bridge design. The matched bridge and bridge plate configuration balances the bass and treble remarkably, and produces sustain unmatched by any other system. There are no sharp corners on the front edge of the bridge to concentrate stress on the top.
