Description
The Sire M6 Headless 4 in Black Swirl is a modern, lightweight bass designed for players who want cutting-edge looks and performance without sacrificing feel or tone. Combining a striking custom-style Swirl finish with Sire’s acclaimed electronics and a super-comfortable neck, it is built to deliver clarity, punch and playability on stage, in the studio and everywhere in between.
With its compact headless design, extended tonal control and premium Marcus Pure-H Revolution pickups, this bass is ready for everything from tight, technical lines to deep, supportive grooves. The sandblasted mahogany and swamp ash body keeps things resonant yet manageable in weight, while the rolled-edge Rosewood Edgeless fingerboard and stainless steel frets make every position feel smooth and precise.
Custom-inspired Black Swirl Finish
The Black Swirl finish brings a look usually reserved for custom shop instruments into the Sire M6 range. Each pattern has its own character, so your bass stands out visually as much as it does sonically. The matte treatment helps reduce glare under stage lights and gives the instrument a sleek, modern feel that complements its headless silhouette.
Comfortable Neck with Edgeless Fingerboard
A 5-piece hard maple and mahogany neck in a familiar C-shape offers stability and comfort across long sets. The Rosewood Edgeless fingerboard, with its rolled fretboard edges, feels broken-in from day one, reducing hand fatigue and making fast runs, slides and position shifts feel natural and effortless. Medium jumbo stainless steel frets add durability and a smooth, consistent playing surface.
Marcus Pure-H Revolution Pickups and Heritage-3 Preamp
The Marcus Pure-H Revolution pickup set works in tandem with the Marcus Heritage-3 preamp to provide a wide palette of usable tones. From tight, articulate fingerstyle to bright slap and warm, rounded lines, the combination of volume/tone, blender, three-band EQ and selectable mid frequency control lets you dial in your sound precisely for any genre or mix.
Headless Hardware for Balance and Portability
The Sire headless individual bass bridge keeps the instrument compact and well balanced, helping to reduce neck dive and making it easier to handle on cramped stages or in the studio. Individual bridge units aid tuning accuracy and intonation, while the absence of a traditional headstock contributes to a lighter overall feel and a more ergonomic playing experience.
