J-Special Deluxe 4 Bass

Basso J-Special Deluxe 4 Alusonic Aluminium Instruments 11

The J-Special Deluxe 4 by Alusonic Aluminium Instruments embodies the balance between classicism and innovation, combining the organic response of wood with the acoustic and visual properties of aluminum or carbon fiber. The lightweight body with a mirror-finish aluminum or carbon fiber top, paired with a selected maple neck, creates a light yet powerful instrument with immediate resonance and a versatile tone.

Thanks to the Alusonic Hybrid Soapbar pickups, this bass offers a wide sound rich in harmonics and can be controlled via passive electronics or, upon request, active electronics. The typical J-bass feel is enhanced by the comfort of the custom neck and perfect balance. An instrument designed for those seeking a bass with a modern character without sacrificing the warmth of tradition.
