Description
The Sire M6 Headless 5 in Blue Swirl is a modern, lightweight bass designed for players who want cutting-edge playability and eye-catching style. Combining a striking custom-inspired Blue Swirl finish with Sire’s acclaimed M6 electronics and a comfortable, extended-scale neck, it delivers powerful, articulate tones that are easy to control in any musical setting.
With its compact headless design, multi-piece neck and premium Marcus Heritage-3 preamp, this bass is built for serious performance. Whether you are holding down tight grooves, exploring technical lines or covering long sets, the M6 Headless 5 offers a fast feel, balanced ergonomics and a wide tonal palette that rewards every touch.
Custom-Inspired Blue Swirl Finish
The Blue Swirl finish brings a look usually reserved for high-end custom instruments into the Sire range. Each finish has its own unique pattern, giving your bass a distinctive visual identity on stage and in the studio. The matte treatment keeps reflections under control under bright lights while still letting the swirling colours stand out.
Comfortable Headless Design
The Sire M-Headless body shape and compact hardware layout make this a highly comfortable bass to wear and play. Without a traditional headstock, the instrument feels more balanced on a strap and in the seated position, helping to reduce neck dive and fatigue during longer sessions. The reduced overall length also makes it easier to transport.
Fast, Extended-Scale Neck
A 5-piece Hard Maple and Mahogany neck provides strength and stability, ideal for a 5-string bass tuned down low. The 33 to 35 inch scale length helps keep the low B string tight and defined, while the C-shape profile and Edgeless Rosewood fingerboard with rolled edges offer a smooth, fast feel across all 24 frets. Stainless steel medium jumbo frets add durability and a slick playing surface for both fingerstyle and slap techniques.
Marcus Heritage-3 Electronics
The Marcus Pure-H Revolution pickup set is paired with the Marcus Heritage-3 preamp, giving you a wide range of usable tones. From deep, rounded lows to bright, cutting slap sounds, the active EQ with middle frequency control lets you fine-tune your sound to the room or mix. The intuitive control layout makes it easy to move from subtle adjustments to bold tonal changes on the fly.
