Solid
Tops and Lacquer Finishes
The sound of an acoustic guitar depends on the vibration of the guitar's
top. Solid tops are made from a very select grade of spruce or cedar
harvested from trees more than 600 years old. The tight, straight grain
in these woods makes them exceptionally strong in the direction of the
grain and therefore able to withstand the string tension. At the same
time, these handpicked tops are very flexible across the grain, which
allows them to vibrate. A solid top instrument will produce richer sound,
more harmonics, and better dynamic range. Virtually every aspect of
the sound of a solid top guitar will be superior to that of a similar
instrument with a laminated (plywood) top.
Equally important to the selection of the guitar's top is the material used to finish it. The thick polyester finishes typically found in all but the most expensive guitars negates all of the potential benefit of a solid top instrument. This is why we spend several days applying a very special lacquer finish to every Norman guitar. This special finish encourages maximum vibration and therefore, excellent sound. Perhaps even more compelling than the great sound of a solid top guitar with a lacquer finish is its capacity to get even better sounding. This is called ageing. The best violins are generally instruments that date back more than a hundred years because these instruments have aged and have become even better sounding over time. The same phenomena exists in solid top guitars. But unlike the great violins, you will not have to wait several decades to hear your guitar at its best. The ageing process in your acoustic guitar begins as soon as you start playing.
Precision
Neck Attachment
The angle of a guitar's neck attachment—often called 'neck pitch'— plays
a crucial role in the instrument’s tone. Simply put, if the neck is
too far back the guitar will lose its bass and sound tinny. On the other
hand, if the neck angle is too far forward the guitar will lose its
high frequency and sound muddy. The Norman neck attachment system ensures
consistent neck pitch. It also produces the added bonus of superior
neck/body energy transfer because the neck is attached to the body wood-to-wood.
There is no glue or finish to impede the vibration between the heel
of the neck and the guitar's body.
Back
& Sides
The body of an acoustic guitar works in a way similar to a speaker box.
In this case the solidtop serves as the speaker and the back and sides
play the part of speaker cabinet. The back and sides of Norman guitars
are made from a three-part hardwood lamination. This special lamination
retains all of the properties of superior tonewoods and provides a solid
foundation for the top. Other standard features on all Norman guitars
include: high-ratio sealed tuning machines, real wood rosettes, double-action
truss rods, custom Tusq nuts, fully compensated saddles, and a limited
lifetime warranty.
