The most important advance since the invention of the electric bass guitar has been the carbon fiber neck. On the performance side, each note is full, with low and high harmonics in generous quantity. The high resonant frequency of carbon fiber drastically reduces dead notes, even when playing the low strings in the high register. Carbon fiber is also impervious to moisture and resilient against changes in temperature. The artistry and craftsmanship of Modulus instruments is unparalleled; from the precision fretwork to the fit of the hardware to the smoothness of the finish, the attention to every detail is obvious and perfect.
