Sigmoidal Sides Joint

Where science meets soul.

A side-joint concept for cleaner transfer and lower mass in the guitar body.

08 / Innovation Lab

The Sigmoidal Sides Joint shapes the connection through the rim so energy transfer can stay clean while unnecessary mass is reduced.

It is part of the construction logic that treats the body as an acoustic system rather than a traditional box.

ARS / X-ARS backs and sides that really sing.

Baltic amber as a stage-visible rosette identity.

Baltic amber as a signature detail.

Curved fret geometry for cleaner contact.

The patented resonant neck system.

Double-top energy control.

Comfort without choking the top.

Side architecture shaped for structural transfer.

Bridge architecture for controlled energy transfer.

Pinless bridge wings with high stiffness and very low mass.

A shifted soundhole for top vibration and clearer player information.

A curved-wood rosette collar that deepens and focuses the air resonance.
