guitars are prized by players for
lightning fast response, elevated volume and presence, tonal
complexity, and the deep golden-brown color of their tops. These
guitars sound different today, however, from the way they
sounded when first strung up. Part of the difference comes from
the effect of many years of playing. Another part is
attributable to the chemical and structural transformations wood
undergoes after decades of natural curing.
Dana’s vision for the
six Aged Tone models
blends vintage appearance and Dana’s exclusive approach to
voicing with the new Aged
Tone finish and the Aged
Tone top .
new Aged Tone tops are treated with a unique curing
process. The commercial version of this process, known as,
“thermo curing”, “wood torrefaction” or “roasting”,
was developed in Finland to enhance durability and appearance of
such products as siding, decking, and outdoor furniture.
Commercial processing typically uses higher curing temperatures
to maximize stability and rot resistance. Higher temperatures,
however, can also sacrifice structural integrity.
The process used to cure our Adirondack tops is a highly
controlled, low-temperature variation of the basic commercial
treatment. During processing, water, sugars, and resins are
cooked off, leaving behind cellulose and lignum--the “glue”
that binds cellulosic fibers together. Once processed, mass and
weight are reduced, absolute stiffness is increased and internal
damping is decreased; stiffness-to-weight ratio and Velocity
of Sound (the rate at which vibration transmits through
solid material) are dramatically increased.
observations concur with industry research data, which reports
increased stiffness at lower curing temperatures. It’s
thought by at least one expert that low-temperature curing
optimizes the distribution of lignum throughout the cellulosic
structure, while higher temperatures break lignum down. The
trick is to find the temperature
and curing schedule that optimizes Velocity of Sound.
naturally cured spruce, Aged Tone tops are darker in
color, opaque vs. translucent, highly stable when exposed to
changes in humidity, and have a sweet, woody smell. These same
changes naturally occur in spruce tonewoods after many decades
of exposure to oxygen, UV radiation and other environmental
the pictures below, we show our standard Adirondack top (on the
left) and a Aged Tone Adirondack top on the right. Neither
top has been stained.
Aged Tone process gives the tops a dark, rich hue, without any
aging toner or finish.
guitars made with Aged Tone Adirondack tops combine
characteristics of both new and vintage guitars. Players
describe their sound as “immediate, “open”, “
responsive”, “loud” and “surprisingly broken in”. New
guitars made with Aged Tone tops will continue to break
in as the top reacts to continuous string loading and
recently developed a light but durable finish to complement Aged
Tone tops. The Aged Tone finish, combines the sound and
look of a well-preserved older finish with the durability of a
modern catalyzed finish.
The Aged Tone
finish began as an effort to replicate the sonic and aesthetic
qualities of older nitro. Nitrocellulose never fully
cures. It starts out thick and soft and becomes considerably
thinner and harder over time. As it cures, weight and mass
diminish, molecules become rearranged, damping recedes and
this transformation contributes significantly to what we
recognize as ‘vintage’ sound.
years of experimentation we found a finish in the cyanoacrylic
family that’s hard enough to exhibit minimum damping, offers
reasonable protection compared to other thinly applied
finishes, and has much in
common with the sound and look of older nitro. Like our
varnish finish, it’s application is both labor and
skill intensive; we’re entirely convinced, though, that the
results are worth the added effort.
Our vision for our new Aged Tone models – a mahogany
and rosewood D, mahogany and rosewood OM and a short scale Slope
D and a DS-Mahogany 12 Fret Slot-head -- blends vintage appearance, a new vintage-style finish,
Dana’s exclusive approach to voicing, and a unique method of

sideman, “For the past 20 years Dana has consistently set the
bar for modern guitar construction, all the while paying homage
to the great guitars of yesteryear.”
