density, moisture , strength and flexibility. They probably do have a solid spruce (or cedar… Spruce and Cedar). The cedar is typically "warmer" and with perhaps less ability to be driven hard. They delineate, protect and define a property. Obviously, there are a plethora of exceptions to consider. Spruce is light in color often described as blonde, or amber and features a tight grain pattern. Fences may be designed to keep animals in, or they may be designed to keep people out. Generally speaking, this is true, but with many individual exceptions. The cedar also may have more overtones than a spruce top guitar, although that definitely depends on how the guitar is built. Mahogany and maple are the most common woods used, with maple more often seen on electric guitars. As an Amazon Associate I earn from qualifying purchases. It’s been said that everything affects tone. The main appeal of Spruce, aside from its availability is its compatibility with many styles of guitar. A plain sawn section of timber is more likely to split, while quarter sawn timber is stronger, more visually appealing and less likely to be compromised when affected by tension. Rosewood is a hardwood but is also quite porous and typically requires grain filling to provide a smooth surface for finishing. So, use Sitka Spruce to brace a Sitka top, German Spruce to brace a German top, and so on. Spruce also tends to project sound in a way that is more linear, as opposed to cedar which has a tendency to “radiate” sound. The three most common species of Spruce used for acoustic guitar soundboard construction are: Sitka Spruce, Engelmann Spruce (European) and Adirondack Spruce. Koa is a hard, dense tonewood that accentuates with mid and upper ranges, providing good articulation and crispness in the upper ranges. In most cases the back and sides will utilise the same timbers. Many softwoods are not sufficiently strong enough to handle the tension placed on the guitar and therefore cannot be used for the guitars soundboard. Cedar is less dense than spruce, and that softness typically translates into a sense of sonic warmth. More often seen as a back and side pairing for acoustic guitars, full Mahogany guitars (soundboard, back and sides) aren’t uncommon however and can look very good. But I'm debating about getting the cedar or the spruce top. Using spruce on the top is the main reason that this guitar enters the slightly brighter, crisper side of the scale. Mahogany is defined as a hardwood but it is perhaps better identified as a ‘soft’ hardwood. This is due to the characteristics of the timber e.g. Maple is often seen as a book matched veneer on electric guitars like the Gibson Les Paul. Tightly grained with a uniform appearance and less discernible grain patterns it’s an attractive timber that tends to look better as it ages. I live far from the nearest music store and have not been able to play one with a cedar top to see for myself. Spruce tends to be the most popular top for acoustics (confusingly there are several varieties of spruce used on guitars!) They are laminated (plywood) and the top ply is a wild cherry finish. Cedar is more responsive to quieter playing and thus has a greater dynamic range, making it ideal for fingerstyle. Timbers used for the neck are mainly chosen for the structural integrity. That’s quite a bit greater than the cedar range. Been playing trad guitar for many years but its hard to try these out as, particularly with the McIlroys as they don’t have stock building up. Posted by Red Dog Music | Acoustic Guitars, FAQ, Guitars, Amps & Effects. Long ago I made a couple of guitars with spruce in the high end of the cedar density range; they were not among my best guitars. Maple is a hard timber and accentuates mid and upper ranges with greater emphasis than Spruce or Cedar for example.
