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

Genesis® and Quantum™ Necks

Modulus instruments feature two types of composite necks, depending on the model. Their original
Quantum bass neck is a lightweight, ultra-rigid “D”-shaped shell made from dozens of layers of
hand-formed aerospace-grade epoxy-impregnated graphite 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 graphite telegraphs attack more
quickly than conventional wood necks, the Quantum neck aids articulation and is dynamically very
sensitive.
 
Genesis guitar and bass necks incorporate a graphite composite spine reaching from the tip of the
headstock to deep inside the body. Wrapped with a solid piece of lightweight, resonant tone
wood, the Genesis neck combines the best elements of graphite and wood. All string tension is
held by the composite central structure to eliminate warping and twisting.  Because the graphite
is handling the stress of the strings, they are able to use soft woods like red cedar, alder and soma
to add warmth and character to the crisp attack characteristics of the composite spine. It’s the
right neck for players looking for organic, woody sound with the added brilliance of composites.

Fingerboard

Genesis guitars and basses feature granadillo, chechen or maple fingerboards. Granadillo and
chechen are ecologically sustainable, independently-certified Mexican hardwoods with similar
characteristics to rosewood and pau ferro. They add a touch of warmth to the midrange of the
instrument and provide a more traditional look and feel than a composite fingerboard.

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.  Their 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.

Commitment to a Healthy Planet

Modulus Guitars is committed to using ecologically-sustainable, independently certified wood in all
its instruments.  Their goal is for 100% of the wood in their instruments to be earth-friendly and
properly harvested.  Through close cooperation with SoundWood, Scientific Certification Systems
and Eco Timber, Modulus pioneers the use of non-traditional woods for electric guitars and
basses. Granadillo, chechen, red cedar, chakte kok and soma are a few of the
exceptional-sounding, ecologically sound woods Modulus offers.

Locking Tuning Gears

Locking tuning gears are standard equipment on Genesis One and Two guitars. They eliminate the
need to wrap strings around the string post, which is the cause of many tuning problems. To
replace a string: Detune the old string until it is completely slack. Turn the locking knob, located
on the back of the tuner counter-clockwise to release the string. Pull the string out of the gear and
feed it back out through the bridge. Feed the new string through the bridge and pull it through the
hole in the tuner shaft. Grasp the length of string beyond the tuner shaft with one hand and pull so
the string is tight, with no slack. Tighten the locking knob on the gear with your other hand until it is
snug. Tune the string to pitch and cut off any excess string beyond the tuner. If the string has been
replaced properly, you will have less than one complete turn of string wrapped around the tuner’s
shaft.
