Double Top

The Origin and Evolution of the Double-Top Guitar

The Double-Top guitar represents one of the most influential innovations in modern classical guitar building. Although the term “Double-Top construction” is not entirely accurate, it has become the standard way to describe a soundboard made of multiple thin layers. A more precise term would be Sandwich or Composite construction, referring to a laminated structure designed to optimise resonance, volume, and responsiveness.

The Invention of the Double-Top

The most renowned method was developed in the 1990s by German luthiers Matthias Dammann and Gernot Wagner. Their design consists of two extremely thin layers of tonewood, usually European spruce or Canadian cedar, separated by a lightweight Aramid honeycomb material (Nomex). This unique combination reduces the weight of the soundboard while maintaining stiffness, allowing the guitar to produce an exceptionally rich and powerful tone.

The Double-Top principle has since inspired luthiers worldwide. Makers such as Jim Redgate, Michel Brück, and Kenny Hill have refined this concept further, each developing their own variations in structure and materials. At Siccas Guitars, you can explore instruments from many of these renowned builders and experience how each interprets the Double-Top idea in their own way.

How Double-Top Construction Works

A Double-Top soundboard combines the best qualities of traditional tonewoods with the precision of modern materials. The outer layers provide the natural warmth and character of wood, while the inner Nomex core adds strength and reduces mass. The result is a soundboard that is both lightweight and highly responsive, improving sustain, projection, and tonal balance.

In addition to the top, many luthiers also use laminated sides and reinforced backs to increase structural rigidity and focus the sound. These laminated components are created by gluing several thin layers of tonewood veneer, resulting in a strong and stable body that enhances both volume and clarity.

Volume and Projection of Double-Top Guitars

Because the soundboard of a Double-Top guitar can weigh up to 25% less than a solid top, it vibrates more freely and produces a louder, more direct sound. The rigid laminated sides help project the sound forward, giving the instrument its characteristic brilliance and presence. However, volume is not the only goal, the Double-Top design also aims to achieve a well-balanced tone across all registers.

It’s important to note that not all Double-Top guitars are automatically louder than traditional models. If the sandwich layers are built too heavy, the weight advantage is reduced. The best instruments strike a perfect balance between strength and lightness to unlock the full acoustic potential of the design.

Responsiveness and Playability

One of the greatest strengths of the Double-Top guitar is its exceptional responsiveness. The lighter top reacts quickly to the player’s touch, producing immediate tonal feedback. Transitions between bright nail attack and rounder, more lyrical tones feel effortless. This agility makes Double-Top guitars particularly appealing to concert players who need dynamic range and expressive precision.

The reduced mass of the top also promotes high overtones, especially near the bridge area, resulting in a lively, complex sound with remarkable sustain and clarity. Many players describe Double-Top guitars as having an almost “singing” quality that enhances their musical interpretation.

The Sound Character of Double-Top Guitars

Double-Top guitars are designed so that certain areas of the top remain slightly more flexible, allowing for subtle tonal variation. The tone is typically clear, open, and highly refined, with a long sustain and strong projection. Some players describe the sound as modern and precise, while others appreciate its warmth and responsiveness that still retains the charm of traditional guitar building.

Many guitarists are surprised by the tonal versatility of Double-Top instruments. If not told beforehand, they often wouldn’t realise they are playing a laminated top, proof of how far this technology has come in achieving natural, musical sound quality.

The Double-Top classical guitar embodies the perfect blend of innovation and craftsmanship. Its unique sandwich construction enhances volume, sustain, and tonal flexibility while preserving the expressive qualities that define fine classical guitars. Whether you are a professional guitarist seeking projection and precision or an enthusiast eager to explore modern luthiery, Double-Top guitars offer an inspiring experience.
