Engelman Spruce
Family: Pinaceae - Order: Pinales - Class: Pinopsida
Scientific
name: Picea engelmannii
Trade name:
Engelmann Spruce
Also known as White Spruce and Silver Spruce
Origin: Western North America
Instrumental uses:
Soundboards, sound bars,
bracing and
bindings.
Tonal properties:
A very refined
and pleasant tonal balance, it reproduces all frequencies but has a
prominent richer midrange which
makes a guitar sound more present with a more
mature sound sending a big projection. Played with nails it can be a perfect
match to guitars with these tops. When used for sound bars and bracing, it can
give with less wood a very good sound optimization and good strength, thanks to
the straight grains usually running for outer side part of the tree with
unparalleled figured grains, especially if very tight.
Very old woods
can produce tops sounding like old matured guitars. Engelmann can match with
several types of back and sides, including Rosewoods, Mahoganies or Maples.
Vintage wood quarter-sawn blocks are
rare and expensive, also the tonal properties are much better.
It is a soft wood but very uniform in
consistency, with an average
dried weight nearly of 24 lbs/ft3 or 385 kg/m3.
