Differences between riftsawn, quartersawn, and flatsawn wood can be significant. Stiffness-to-weight ratio, highest when boards are perfectly riftsawn, drops noticeably when a top is cut even slightly different. Velocity of sound—the ability to vibrate efficiently—corresponds closely with stiffness-to-weight ratio.

Perhaps because of their lighter weight, cedar and redwood tops tend to “open up,” or break in, relatively quickly. However, unless the builder pays adequate attention to longitudinal stability, cedar and redwood tops sometimes open up beyond a point that many players consider optimal, losing low-end definition as the guitar continues to be played.

Ask the Expert: Should I Reset the Neck on My Vintage Guitar?
Guitars sound best when string load and top resistance are in relative balance. An underloaded top cannot drive enough air to achieve optimum volume, power, and presence; an overloaded top is unable to generate higher overtones and lacks sustain. One key to optimizing the mechanical efficiency of an individual top is knowing, with some precision, how it wants to be loaded.
