Exploring Purpleheart as a Tonewood

When crafting guitars, selecting the right tonewood is crucial. While sound quality is paramount, the aesthetic appeal of the wood also plays a significant role. Enter purpleheart—a wood that stands out for both its visual allure and density. But is purpleheart a worthwhile tonewood? This article will delve into what you need to know about it.

Understanding Purpleheart

Purpleheart, also known as amaranth, is sourced from the Peltogyne genus of trees. It's a hardwood native to the rainforests of Central and South America, mainly Brazil. Known for its incredible durability, one of its most appealing features is its vibrant color—aptly named. The heartwood starts as a light purplish-brown when freshly cut and evolves into a rich purple after exposure to air. Unfortunately, over time and with UV light exposure, this color fades to a deep purplish brown.

Using Purpleheart in Guitar Construction

Due to its density, purpleheart has specific applications in guitar making, though it isn't suitable for every part of the instrument.

Purpleheart is a heavy wood, about 30% denser than mahogany, which is already quite weighty. This makes it less ideal for solid guitar bodies, where lighter and more workable alternatives like maple are preferred. It might be used as a top wood, but there are easier options available.

In acoustic guitars, purpleheart is favored for backs and sides, producing a balanced tone with warm bass, clear highs, and pronounced midrange. Its clarity and projection are excellent, though the effort required to work with it means it's not often used by major brands for guitar bodies.

The wood's strength makes it suitable for necks, but its weight could cause neck dive, so it's more often seen in laminated necks. It shines most on fretboards, where its strength and projection require less preparation.

Sound Characteristics of Purpleheart Guitars

Purpleheart offers a rich and deep tonal range, with bright, warm highs and mids, complemented by a responsive bass. Its natural density contributes to a longer sustain, with each note fully resonating. The hardness of the wood also results in strong projection, making it suitable for both solo and group performances.

The wood's nuanced harmonics and dynamic range add complexity to the guitar's sound, providing clarity and fidelity whether playing chords or solos.

Sustainability of Purpleheart

With environmental protection being critical, many traditional tonewoods like rosewood and ebony face sustainability challenges. How does purpleheart fare?

Native to the rainforests of Central and South America, purpleheart faces deforestation pressures. However, sustainable forestry practices and certifications like the Forest Stewardship Council (FSC) help ensure responsible harvesting. Purpleheart isn't listed in the CITES Appendices, and the commonly harvested Peltogyne species aren't on the IUCN Red List, making it a viable choice for environmentally conscious guitarists.

Durability and Maintenance

Purpleheart's density ensures excellent durability, making it ideal for those prioritizing longevity and robustness. It's resilient on necks and fretboards, resistant to wear, humidity, and temperature changes. Maintenance is straightforward: wipe the fretboard during string changes, possibly using a little isopropyl alcohol for stubborn dirt, and consider a quality fretboard oil.
