Located in the heart of the thriving San Francisco Bay Area music scene, Modulus Guitars began building exceptional handmade instruments in 1978.  Our specialty is utilizing innovative materials to better serve the needs of the serious player.  Modulus pioneered the use of carbon fiber in the construction of guitar and bass necks.  We were the first to combine structural carbon fiber with non-structural tone woods in our Genesis guitars and basses. We were also the first to commit to using independently certified woods for every aspect of instrument building.

Quantum Neck

Our original Quantum bass neck is a lightweight, ultra-rigid “D”-shaped shell made from dozens of layers of hand-formed aerospace-grade epoxy-impregnated carbon fiber fibers. With an amazing strength-to-weight ratio and a  resonant peak far above the range of the notes on a bass, it is an ideal neck for producing crystal clear, even tone.  Because the carbon fiber telegraphs attack more quickly than conventional wood necks, the Quantum neck aids articulation and is dynamically very sensitive.

Fingerboard

Composite boards are denser and harder than a wood fingerboard, offer similar performance to ebony and will not shrink or crack. The harder material adds a bit of extra high end sizzle on fretted basses, and a tighter focus to the sound of fretless instruments.

Wood

Modulus instruments are crafted from the finest aerospace-grade composites and hand-selected exotic woods.  Wood, whether for the body of a Quantum bass or the neck of a Genesis guitar, is chosen for its tonal characteristics, beauty and long-term stability. Our skilled builders combine woods to create instruments with individual sonic and visual character that maintain the signature Modulus sound: Crisp and clear with warmth and dynamic sensitivity.
