From the Sire modern bass series, we introduce another contemporary instrument, the new M6 Headless. Its design is distinctive compared to previous Sire models, weighing less than 3.6 kg (based on the 4-string version) to prevent the "neck dive" effect and ensure greater comfort and balance during playability.
Equipped with a preamp and multiple switches, it is a highly versatile bass, ideal for genres such as pop, rock, metal, blues, and more. The M6 Headless features 24 frets and is available in 4, 5, and 6-string versions. It includes premium DR Dragon Skin+ bass strings and the official Sire gig bag.
