Vertical Grain Matters
Vertical grain (as one might expect) is the lines that are almost straight up and down on the flat face of a boarded cut. If the guitar craftsman is able to avoid runout (the twisting of wood), guitar makers are able to provide a better soundboard. Minimal runout is an indicator of strong, stiff and durable wood. Conversely, if the wood has runout and is stressed, the wood is more likely to break and will have an adverse effect on the sound of the instrument. The closer you are to a true vertical grain, the better off the soundboard will be. Although some soundboards need weaker boards due to the unique style of the guitar, the overwhelming majority will have a superior sound when the soundboard is stiff. Simply put, vertical grain is an important, yet often overlooked aspect in the construction of your instrument. If you have any questions, please let us know.
