How Nitrocellulose Lacquer Affects the Sound of a Guitar
If you are a guitar player or enthusiast, you’ve probably heard about the nitrocellulose lacquer finish commonly used on guitars. Many guitar players swear by the unique sound and feel of nitro finishes, and it has become a hallmark of high-end guitars. But what exactly is nitrocellulose lacquer, and how does it affect the sound of a guitar? In this blog post, we’ll take a deep dive into the world of nitro finishes and explore the ways it affects the sound of a guitar.
What is Nitrocellulose Lacquer?
Nitrocellulose lacquer is a type of finish used on guitars, as well as other musical instruments, furniture, and cars. It’s made by dissolving nitrocellulose, a polymer that is commonly used in gunpowder and other explosives, in a mixture of solvents and additives. The resulting lacquer is then sprayed onto the surface of the guitar, where it forms a hard, durable, and glossy finish.
Nitrocellulose lacquer has been used as a guitar finish since the early days of the electric guitar. It was originally developed as a way to protect the wood from wear and tear, but it soon became apparent that it had other benefits as well. Nitro finishes are easy to repair and modify, and they give the guitar a vintage look and feel that many players find appealing.
Nitrocellulose Lacquer and Sound
One of the most significant ways that nitrocellulose lacquer affects the sound of a guitar is through its impact on resonance. Resonance is what gives a guitar its distinctive tone and sustain, and it’s influenced by many factors, including the quality of the wood, the hardware, and the finish. Nitrocellulose lacquer is particularly effective at enhancing resonance because it’s a thin coating that doesn’t impede the wood’s ability to vibrate.
When a guitar is played, the wood vibrates, and the sound waves are transferred through the body and the neck to the strings. The strings vibrate in response to the sound waves, creating a feedback loop that amplifies the sound. Nitro finishes allow the wood to vibrate more freely, which enhances the resonance and sustain of the guitar. The result is a guitar that is more responsive, with a richer and more complex sound.
Another factor that affects the sound of a guitar is the way that the finish affects the wood’s aging process. Wood is a natural material that changes over time as it’s exposed to air, temperature, and humidity. Nitro finishes allow the wood to age naturally, which can produce a warmer and more mellow tone over time. The aging process also produces cracks and dings in the finish, which can give the guitar a unique character and a vintage look that many players find appealing.
Nitrocellulose Lacquer vs. Polyurethane
While nitrocellulose lacquer has many benefits, it’s not the only option for guitar finishes. Another popular choice is polyurethane, a synthetic material that is known for its durability and resistance to wear and tear. Polyurethane finishes are often used on less expensive guitars and have a reputation for being less resonant and less comfortable to play than nitro finishes.
Polyurethane finishes can be thick and stiff, which can impede the wood’s ability to vibrate. This can result in a guitar that sounds dull and lifeless, with less sustain and resonance than a guitar with a nitro finish. However, polyurethane finishes are more resistant to damage, and they don’t age in the same way as nitro finishes. This means that a polyurethane-finished guitar may retain its shiny new appearance for longer, but it may not develop the same character and warmth over time as a nitro-finished guitar.
Conclusion
In conclusion, nitrocellulose lacquer is a popular and versatile guitar finish that has a significant impact on the sound of a guitar. Nitro finishes enhance resonance and sustain, allowing the wood to vibrate more freely and producing a fuller and more complex sound. They also allow the wood to age naturally, producing a warmer and more mellow tone over time. While there are other finish options available, including synthetic materials like polyurethane, many players prefer the unique character and vintage feel of a nitro-finished guitar.
If you’re considering a new guitar, it’s worth taking the time to learn about the different finish options and how they affect the sound and feel of the instrument. Whether you prefer the classic and timeless look of a nitro-finished guitar or the durability and resilience of a polyurethane finish, there’s a finish out there that will meet your needs and help you create the music you love. So, go out there and experiment with different finishes to find the one that suits your style and personality.
