Acoustic Resonance System
Our ARS / X-ARS backs and sides are engineered to move as one. The result is greater harmonic richness, faster response and a voice that opens with every note you play.

Tuned movement.
Natural voice.
ARS (Acoustic Resonance System) and X-ARS (eXtended Acoustic Resonance System) are exclusive Turkowiak approaches to the voice of the guitar.
They coordinate the resonant behaviour of the back and sides with the top, creating a unified instrument that amplifies nuance without effort.
