Double-top guitar construction
what does it mean?
A double-top classical or acoustic guitar (also called “composite top” or “sandwich top” is a type of guitar that features a guitar top made of two layers of tonewood (same kind or different) separated by material like nomex ( a kevlar polymer, manufactured in a honeycomb pattern, originally developed for the aviation industry), balsa wood or other (sometimes being a secret of the guitarmaker) this way that, there are many empty (air filled) spaces. Such guitars were pioneered by German Luthiers Gernot Wagner and Mathias Damman.
Double-top is not as thin as lattice braced top and behaves, acoustically speaking, much more like a traditional solid top guitar.
The purpose of this concept is to increase the amount of sound energy that is emitted from the guitar’s soundboard, without increasing the weight of the guitar. This results in a guitar that has a louder, more responsive sound and improved projection. Additionally, the use of a double top can also help to improve the overall stability of the guitar, as the additional layer of material helps to stiffen the soundboard and reduce the risk of warping or cracking.
The construction of this kind of guitar top is a complex and time-consuming process, and it requires a high level of skill and expertise. The lamination process must be done with precision and care, as the slightest misalignment or imperfection can have a negative impact on the guitar’s sound and structural integrity. Additionally, the bracing and internal construction of a double-top guitar must also be carefully designed and executed to ensure that the guitar is both structurally sound and acoustically optimal.
Overall, a double-top classical guitar is a high-end instrument that offers many benefits over a traditional single-top guitar, including improved sound, projection and stability.
Several guitar makers construct double-top classical guitars, some of the well-known luthiers and companies that construct double-top classical guitars are:
– Gernot Wagner: He is a German luthier who is considered one of the pioneers of the double-top guitar construction. He is known for his high-quality double-top guitars and his unique approach to the construction process.
– Rafał Turkowiak – an innovative polish luthier.
– David Skolnick: He is an American luthier who has been building double-top guitars for many years. His guitars are known for their excellent sound and craftsmanship.
– GSI (Guitar Salon International): They are one of the most well-known distributors of double-top guitars, representing several luthiers and brands that construct double-top classical guitars.
– Dario D’Attis: He’s an Italian luthier, who is known for his high-quality double-top guitars.
– Daniel Friederich: He is a French luthier who is considered one of the leading makers of double-top guitars. His guitars are known for their exceptional sound quality and craftsmanship.
Double-top classical guitars are typically used by professional and advanced level classical guitarists. These guitars are designed to offer improved sound, projection, and stability, which makes them well-suited for concert performances and recording sessions.
Many professional guitarists and performers choose to play double-top guitars because of the increased volume and projection they offer. This can be especially beneficial in large concert venues or when playing with a full orchestra. The improved sound and projection also make double-top guitars well-suited for recording sessions, where the guitar’s sound needs to be captured accurately and clearly.
Additionally, double-top guitars are also used by guitar teachers and students who are looking for a high-quality instrument that can support their learning and performance.
It’s worth noting that double-top guitars are typically more expensive than traditional single-top guitars, so they may not be as accessible for beginner or intermediate level players.
