Do Guitar Finishes Affect Sound?
As a guitarist, you might have wondered whether the finish on your guitar affects the tone it produces. After all, a guitar is a complex musical instrument made of different materials and components, each of which contributes to its sound. The finish is one of those components, and it may have a significant impact on the guitar’s sound quality. In this blog post, we will dive into the topic of guitar finishes and how they affect sound.
Before we dive in, let’s define what we mean by the guitar finish. The finish is the protective layer on top of the wood. The finish can be either glossy or matte, and it can have varying levels of thickness. The most common finishes are polyurethane, nitrocellulose, polyester, and shellac.
How does the thickness of finish impact tone?
The thickness of the finish on a guitar can impact tone. Thicker finishes impede vibration and can dampen the tone of the guitar. The thicker finish can cause the guitar’s tone to be less bright, less resonant, and less dynamic. The thinner the finish, the more the wood can vibrate, and the more vibrant the guitar’s tone will be. As such, many guitar players believe that thin finishes are better for tone compared to thicker finishes.
The thickness of the finish can vary depending on the type of guitar. Acoustic guitars commonly have thinner finishes compared to electric guitars. This is because thicker finishes can negatively impact the projection and sustain of an acoustic guitar. Electric guitars can have thicker finishes because they rely more on pickups to amplify the sound. However, some electric guitar players also prefer thinner finishes on their guitars for better tone.
Does a glossy finish resonate differently than a matte finish?
Another factor that affects tone is whether the finish is glossy or matte. The difference between a glossy finish and a matte finish is that a glossy finish is a lot smoother than a matte finish. The glossy finish reflects light and creates a sleek, shiny appearance. In contrast, a matte finish is a bit more textured and reflects less light, making it less shiny than a glossy finish.
However, it is not a simple conclusion to say that one finish resonates differently than the other. The finish itself does not have the ability to affect the tone of the guitar. The finish only affects the way the wood vibrates and the way sound waves bounce off the guitar’s surface. The finish does not influence how the strings and pickups interact with the guitar.
In terms of the guitar finish, the most essential factor is the thickness of the coating. As we mentioned earlier, a thicker finish will impede the vibration of the wood, causing the tone to be less dynamic. On the other hand, a thinner finish will allow the wood to vibrate more naturally, resulting in a more unusual and lively tone.
Which finish is best for your guitar?
Now that we have discussed the impact of finish on tone, the question arises: which finish is best for your guitar? The answer to that question is that it depends on personal preference and style of play. If you are a fan of a brighter and livelier tone, then a guitar with a thin finish is an excellent choice. If you prefer a smoother and more controlled tone, a thicker finish could work better for you.
There are also other factors to consider when choosing a finish for your guitar. The type of wood used in the guitar’s construction can affect how the finish behaves on the guitar. The finish can also change over time, so it is essential to consider the long-term changes that can occur with your finish of choice. For example, nitrocellulose finishes are known to age gracefully, whereas polyurethane finishes can crack and peel over time.
Regardless of the finish type, it is always best to choose a high-quality finish. A high-quality finish will be applied evenly, maintain its color and shine over time, and provide excellent protection for the guitar’s wood.
Conclusion
In conclusion, the guitar finish can affect the sound quality by how it impacts the wood vibration. However, the difference between matte and glossy finishes does not influence tone in the same way. The thickness of the finish is and will always be the deciding factor. As a guitarist, it is essential to choose a finish that complements your playing style and personal preference. Ultimately, it is up to the player to find the right balance of beauty and sonic excellence in their guitar finish.
