Acoustic Guitar Tone Woods a écrit : IF ALL OTHER THINGS ARE EQUAL, that is, if we're talking about guitars of the same model, size and detail of construction, by the same maker, with the same neck angle, bridge height, top thickness, species of top wood, age, then it appears:

A wide grain top will tend to produce stronger bass response. That's because there are fewer stiff grain lines so the top is more flexible. From the flexibility comes a lower natural resonant frequency and more easily produced bass notes.

A narrow grain top will have comparatively stronger treble and more subtle bass. This top has lots of hard grain lines, is much stronger and has a higher natural vibrating frequency.

It's a ninety year old Gibson mandolin with just about the most uneven looking spruce grain I've ever seen in a good instrument's top. The two halves aren't matched at all (not unusual for early Gibson mandolins, by the way) and the treble side has the widest grain imaginable. And, wouldn't you know it, this instrument is exceptionally good sounding, and there is not the least sign of structural failure in the top!
