In 1995, Bob Taylor used top wood cut from a 2×4 (“pine, fir, or hemlock”) and back wood from an oak pallet salvaged from a dumpster to build a guitar. Roger Bucknall (Fylde Guitars) routinely uses top wood of Oregon pine from distillery washback vessels and back and side wood salvaged from oak whisky casks for his “single malt” guitars. C.F. Martin & Company builds guitars with backs and sides made from high-pressure laminates with composite fretboards, materials of a type more commonly found surfacing kitchen workbenches. On its website, Martin claims that its wood-topped HPL guitars have the “sound of a highly collectible Martin,” presumably invoking comparisons to red spruce/rosewood instruments. The claims made by these makers for the sound of such instruments make the point that building a good guitar depends more on the skill of the luthier than on the quality of the materials that are used. In 1862, the great Antonio de Torres proved his point by building a guitar with papier-mâché back and sides so, as one legend goes, to demonstrate the primacy of the soundboard in guitar construction. I, too, have built a guitar using reclaimed wood from a building renovation. It had a five-piece radiata pine top and meranti back and sides. It sounds better than the majority of guitars that you can buy in a main-street store.

How the second matter is handled is arbitrary, depending on the acoustical preferences of the builder, but the first matter is nonnegotiable if the instrument is to survive the applied string loads. So our concern here is principally with the first matter. Spruce has been the wood of choice for guitar braces for over a hundred years and a relatively simple analysis will demonstrate why this is the case. To illustrate the point, a possible alternative wood, in this case western red cedar, has been chosen for comparative purposes. The significant material properties are tabulated below (Table 1), these values being for specific samples that I tested.
