Liutalab

Improve your guitar's sound, craft your perfect instrument!

Liutalab is the essential tool for luthiers who want to understand the mechanics of their instrument and avoid costly mistakes.

The secret to a powerful, resonant guitar lies in the correct flexural rigidity of the soundboard. Liutalab lets you calculate it precisely — no more guesswork.

WHAT YOU CAN DO

Calculate the ideal thickness of the soundboard based on string tension and wood properties.

Design brace dimensions for any bracing pattern: X-bracing, Fan, Falcate, or Lattice.

Verify the actual rigidity of your soundboard before gluing it to the ribs, using the built-in deflection-based stiffness check.

MATERIALS DATABASE

Choose from the most common tonewoods — Spruce, Cedar, Sitka, Balsa — or enter your own measured Elastic Modulus for maximum accuracy.

TARGET REFERENCE VALUES

Liutalab provides benchmark flexural rigidity values for different instruments:
· Classical guitar
· Acoustic guitar
- Ukulele

SAFE EXPERIMENTATION

Design and test new bracing patterns and immediately see how they affect the structural behaviour of the soundboard before committing to a build.

Liutalab is built for professional luthiers, students of lutherie, and anyone who wants to go beyond intuition and truly understand their instrument.
