Foster Guitars Tech Tip April 25, 2015
In
Guitar building the fingerboard wood affects both the look and sound of the
finished guitar. There are many choices available but the three main wood types
used for fingerboards are rosewood, maple, and ebony. WT. Foster Guitars
primarily used rosewood and ebony fretboard wood, after many trial and error
sample neck and sound sampling, we are now offering maple fretboard on select
models available later this summer. Below is a summary of the 3 main fretboard
woods, we hope this sheds a little light or clarity on the different values and
effects on tone by using each type of wood. These findings are subjective as for
the effect on the tone or sound of the guitar, it is a more personnel
preference than actual tonal difference. The actual change in tonal characteristics
by the different fretboard wood are slight but could make all the difference in
the world to individual players.
Rosewood
Is
the most commonly used wood for fingerboards in the guitar industry. Rosewood
has an open porous grain and has natural oils giving rosewood a smooth feel and
“warm tone”. It has a medium density that is less reflective than harder
woods with a tighter non porous grain, giving rosewood a slightly softer feeling
fingerboard. There are a variety of rosewoods, the most used by instrument
makers is Indian rosewood. Indian rosewood has the familiar rich, darker brown
color with even grain, with the availability and comparable lower cost of
Indian rosewood this makes it a preferred choice for instrument manufacturers. Then
there is Brazilian rosewood another favored variety but limited availability
makes it costly for most guitar manufacturer to use on stock instrument and is
usually reserved for custom shops and high end stock.
Ebony
Combines
the hardness and density of maple with the natural oils of rosewood, ebony is
generally used as an in between fretboard wood offering the best of both worlds.
Ebony has a consistent blackened color that is appealing to the aesthetics of
guitars. The tight grain and natural oils in ebony offers a smooth glassy feel
with a more “crisp and snappy tone”.
Maple
Maple
is a light colored and very tight grained wood. Maple is a very stable wood,
has “bright tonal quality”. Maple is almost always finished due to its
lack of natural oil. Generally gloss or satin clear coat is used some manufacturers
use tung oil as another option. Availability and re-growth make maple a highly sustainable
wood choice and have some manufacturers experimenting with a curing process
known as “baked” This gives maple a softer feel and sound with a rosewood type appearance.
Moisture is also infused into the wood during torrification so clear coat is not
used.
