Gibson SG 61 Standard Finish Cracks Under Binding A Cause For Concern
Introduction: The Gibson SG 61 Standard and Finish Cracks
The Gibson SG 61 Standard is a legendary guitar, revered for its iconic design, powerful sound, and historical significance in rock and roll. Known for its thin, lightweight mahogany body, dual humbucker pickups, and fast-playing neck, the SG 61 Standard has been a favorite among guitarists across genres for decades. However, like many guitars, it is not immune to certain issues. One common concern among owners of these instruments is the appearance of finish cracks under the binding. This issue can cause anxiety for guitar enthusiasts who treasure the aesthetic and structural integrity of their instruments. In this article, we will delve deep into the matter of finish cracks on a Gibson SG 61 Standard, specifically focusing on cracks that appear under the binding. We will explore the causes of these cracks, differentiate between cosmetic and structural problems, discuss whether such cracks are a cause for concern, and examine the best approaches to address and prevent them. Understanding the nature of these finish cracks is essential for any SG owner looking to maintain the beauty and playability of their cherished guitar.
What are Finish Cracks?
Finish cracks, often referred to as lacquer checking, are fissures that appear in the guitar's finish over time. These cracks are usually superficial and do not necessarily indicate a structural issue within the wood itself. The finish on a guitar, typically nitrocellulose lacquer, is applied to protect the wood and enhance the instrument's appearance. However, this finish is susceptible to expansion and contraction due to environmental changes, such as temperature and humidity fluctuations. When these changes occur rapidly or drastically, the finish can develop small cracks as it ages and loses its elasticity. While finish cracks might seem alarming at first glance, they are a fairly common occurrence in older guitars and even some newer ones. These cracks often appear as fine lines running along the grain of the wood or around areas where different materials meet, such as the binding.
Why Cracks Appear Under the Binding
The area where the binding meets the guitar's body and neck is particularly prone to finish cracks for several reasons. The binding, usually made of plastic or celluloid, has a different rate of expansion and contraction compared to the wood and the finish. This disparity can create stress points along the binding edges. As the guitar ages and is exposed to varying environmental conditions, the differing rates of expansion and contraction between the binding, wood, and finish can lead to the development of cracks. The finish in these areas is under constant stress, making it more likely to crack over time. Moreover, the binding itself can sometimes exert pressure on the finish, especially if it was not perfectly fitted during the manufacturing process. This added pressure, combined with environmental factors, increases the likelihood of finish cracks appearing under the binding. The appearance of these cracks doesn't always indicate a serious problem, but it is essential to understand the underlying causes to determine the best course of action.
Cosmetic vs. Structural Issues
It is crucial to distinguish between cosmetic finish cracks and those that indicate a structural issue within the guitar. Cosmetic cracks are superficial and only affect the finish layer. These cracks do not compromise the structural integrity of the instrument and are often considered part of the guitar's natural aging process, adding character and vintage appeal. On the other hand, structural cracks are more severe and extend beyond the finish into the wood itself. These cracks can affect the guitar's stability, playability, and sound. Signs of structural issues include large, deep cracks, cracks that widen over time, or cracks accompanied by changes in the guitar's action or intonation. Cracks around the neck joint or headstock are particularly concerning, as these areas are under significant stress. If you notice cracks that seem to be more than just surface-level, it is crucial to have the guitar inspected by a qualified luthier. A professional assessment can help determine the severity of the issue and recommend the appropriate repairs. Understanding the difference between cosmetic and structural problems is essential for maintaining your guitar's health and longevity.
Is it a Cause for Concern? Assessing the Severity of Finish Cracks
Determining whether finish cracks on your Gibson SG 61 Standard are a cause for concern involves a careful assessment of their nature and extent. While some cracks are merely cosmetic and do not affect the guitar's playability or structural integrity, others may indicate more significant issues that require attention. It's essential to evaluate the cracks' location, size, and depth, as well as any associated symptoms, to gauge the severity of the problem.
Evaluating the Cracks
Start by evaluating the cracks closely. Cosmetic cracks, as mentioned earlier, are usually fine lines that appear on the surface of the finish. They often follow the wood grain or occur along the binding edges. These cracks are generally stable and do not change significantly over time. They might even add a vintage aesthetic to your guitar, similar to the
