Math Seven Strings is a hollowbody arch top with a 16-inch body, which imposes particularly strict criteria for choosing the woods, setting thicknesses and structural solidity, to guarantee the tonal and volume balance to the complex dynamics of the seven strings. The neck is equipped with a strong truss rod of particular quality, always reinforced with titanium, assisted by the presence of two carbon fiber strips. This virtually nullifies the possibility of unwanted movements and twists of the mahogany neck, which is appropriately seasoned with the natural method. The parameters and dimensions of the body, neck and fingerboard are fully customizable, to optimize the musician’s approach to the characteristics of this particular instrument, with its multiple expressive potential. The “piezo” option is highly recommended, as it expands the possibilities of use.
