Modern acoustic guitar

The modern acoustic guitar became established throughout the 20th century as a technical and aesthetic development arising from the traditions of the classical guitar and concert plucked-string instruments. Increasing demands for sound projection, dynamic response, and timbral versatility led to the development of new constructive solutions, particularly in soundboard design, internal bracing structures, and the careful selection of materials.

Within this context, the instrument presented here engages with this historical lineage, integrating consolidated acoustic principles with contemporary approaches to lutherie, aiming for a balance between sound power, clarity, and expressive control.

Constructive Characteristics

  • Scale length 654 mm (25.4″)

  • Bracing system X-bracing, aiming for sound projection, spectral balance, and controlled dynamic response

  • Soundboard Engelmann spruce (Picea engelmannii), selected for its balance between stiffness and lightness

  • Back and sides Imbuia (Ocotea porosa), with a central maple strip (Acer pseudoplatanus), contributing to structural stability and visual identity

  • Neck Spanish cedar (Cedrela odorata), promoting lightness and ergonomic comfort

  • Fingerboard and bridge Muirapiranga (Brosimum rubescens)

  • Purflings Maple (Acer pseudoplatanus)

  • Finish Oil finish, carefully applied to preserve the vibrational integrity of the instrument
