J-Special Supreme 4 Bass

Basso J-Special Supreme 4 Alusonic Aluminium Instruments 11

The J-Special Supreme 4 by Alusonic Aluminium Instruments represents the pinnacle of Alusonic’s technical and sonic research. The body is fully milled from a single block of aircraft-grade aluminum, offering a unique combination of structural rigidity and extremely defined tonal response. The maple neck with graphite reinforcements ensures stability even in extreme conditions, while the Graphitex fretboard guarantees a modern and responsive playability. The Alusonic Hybrid Soapbar pickups combine Alnico5 and Neodymium magnets for a wide tonal range, from crystal-clear definition to full-bodied lows.

This bass is designed for those seeking something truly unique, futuristic, and built to last. Crafted with the typical care of Made in Italy, it is delivered with a hard case and certificate of authenticity.
