Rosewood
Exploring Alternative Tonewoods For many years the crème de la crème of tonewoods was Brazilian rosewood. Brazilian rosewood is sought after for its dark brown color that ranges from chocolate brown, to rust or a warm burnt orange. Finer examples feature fine black line figuring and spider webbing. Some say the tone is incomparable; great projection, with strong, balanced bass and highs are its trademarks. Though this wood is still in common usage, it has been protected against import and export by the CITES Treaty.

The main alternative is Indian rosewood, which has become such a standard choice that it should now be considered a traditional tonewood itself. Basically brown, but with purple, gray and sometimes red highlights, it is known for straighter, more homogenous grain lines and a lack of ink-line figuring. Some say it is on par with Brazilian rosewood for tone, and it is far easier to procure and less expensive.


Rosewood Alternatives
There are a number of other woods that, because of their higher density, help create a rosewood-like sounding guitar, but do not come from the rosewood family. Visually, none of them would be mistaken for rosewood, but they are all quite attractive in their own right.

Exploring Alternative Tonewoods On the higher-end are Macassar ebony and ziricote. Macassar ebony is a black wood with dramatic blond streaking which creates a beautiful liquid or marbled appearance. Ziricote is grayish and features intense spider- web figuring and layered effects. Both woods are brittle and hard to work with, and both are expensive; however, their high density allows for great tonal balance and volume and the scarcity of well-figured sets adds value to the instruments.

The remaining rosewood alternatives are relatively inexpensive and easy to come by. From Africa there’s bubinga, which has a nice reddish-mauve brown color and often sports an interesting “bees-wing” figure that gives a nice three-dimensional shimmer to wood under finish. Also from Africa is padauk, a brilliant purple-red wood that oxidizes to dark brown over time. Finally, there is wenge, a very dark brown wood (verging on black) that some well-known builders, such as Mark Blanchard, have had good results with.

Exploring Alternative Tonewoods From South America there is grenadillo. This wood has a nice purple brown color reminiscent of Indian rosewood, except that it does not have the straight lines that Indian has. Grenadillo does have a subtle wavy figure, a bright responsive tap tone, and attractive sapwood centers are commonplace. It is popular in Brazil, but it is relatively new to American lutherie. It promises to become a favorite among steel-string builders.

Pau ferro (or morado) is well known as a fingerboard wood on electric guitars and basses and is coming into its own as a back and side wood. It is much like Indian rosewood with dark, straight, vertical lines except that gold, beige and brown substitute for the dark browns, grays and purples found in Indian rosewood.


Mahogany
Genuine Honduran mahogany has been an ideal choice for a variety of woodworking applications. Its cross-grained structure makes it unusually stable and easy to carve. It is a superb choice for woodcarvings, furniture making and pattern making. It is still the most popular choice by far for guitar necks, though Spanish cedar is widely used on classical guitars and maple is widely used on electric guitars.

Exploring Alternative Tonewoods Genuine Honduran mahogany was once in plentiful supply, but it is now nearing CITES treaty protection. The guitar-making world is struggling to find a suitable alternative for necks, but there is really no clear choice. Fortunately, the use of truss rods and graphite reinforcement in necks will allow the luthier to accept other mahoganies that are not quite as stable without any ill effects.

As a back and side wood, mahogany has sometimes been considered a “poor man’s choice,” but there is now a great appreciation for its unique tonal qualities. It seems that mahogany ages well and its true value may not reveal itself until a few years have passed. This is especially true when it is used as a top wood (Martin issues a mahogany-topped model from time to time). Mahogany’s trademark tone is a powerful midrange, with great punch and character.


Mahogany Alternatives
Exploring Alternative Tonewoods As far as stability is concerned, Honduran mahogany has no peers, but tonally there are some good alternatives. The best is Sepele mahogany, which features a very attractive ribbon figure that runs parallel to the grain. Khaya mahogany looks more like Honduran but is generally softer, so it is important to find dense logs when cutting for guitar material.

Outside of the mahogany species, lacewood is the most exciting alternative. According to John Greven, a luthier who has built hundreds of guitars in his career and who has a great respect for vintage Martins, lacewood has the rare ability to impart the tone of a well-aged Martin mahogany guitar to a brand-new instrument. Fruit tree woods, most notably cherry and pear, sometimes draw comparisons to mahogany.


Where to Now?
Remember, each piece of wood is different and what each luthier does with the wood is unique. You can read about woods all you want, and you can tap and flex the individual pieces to test their tonality, but you will learn far more by playing the instruments themselves. Keep an open mind when searching for a new guitar, or when having one custom built. What a luthier might suggest may surprise you. Though tradition may direct you to select a guitar made out of this or that wood, your dream guitar may very well be born of a unique, and heretofore unheard of tree!
