Essential Information About the Sire M6 Headless 4 "Black S" Bass

  • Lightweight headless design (? 4 kg max in 4-string version) for excellent balance and less fatigue during long sessions.
  • Huge versatility thanks to the Marcus Heritage-3 3-band preamp, active/passive mode, and pickup variation switches.
  • Modern ergonomics: 24 frets, multiscale 33"?34.5" scale length for even tension and precise intonation.
  • Premium woods and craftsmanship: swamp ash "Black S" body and 5-piece maple/mahogany neck for stability.

Sire?s First Headless in the Marcus Line

The M6 Headless introduces the "headless" approach at Sire, a brand renowned for its basses co-developed with Marcus Miller. It sits at the top of the modern M series, carrying the Sire sonic DNA while adding contemporary ergonomics: lightweight, perfect balance sitting or standing, and full access to all 24 frets.

Who Is It For and What Styles?

Designed for intermediate to expert bassists seeking a reliable instrument for both stage and studio. Its active/passive electronics and numerous controls effortlessly cover pop, rock, metal, funk, fusion, R&B, and blues. The headless design and multiscale scale length promote precision, speed, and comfort?ideal for modern fingerstyle, pick, or slap playing.

The Sound

The swamp ash body delivers attack, projection, and clarity in the highs, while the rosewood fingerboard softens the high frequencies for a warm low end. The Marcus Pure-H Revolution set provides a punchy, quiet tone with great midrange definition. The Heritage-3 preamp offers master volume/tone, pickup blend, bass, treble, and parametric mid controls (gain + frequency), plus an active/passive switch to switch from a modern, sculpted character to a more organic voice. The multiscale 33"?34.5" scale length optimizes string tension individually, delivering tight lows, a deep B/E, and precise highs, with enhanced sustain thanks to the 5-piece neck.

Recommended Compatible Accessories

To fully exploit this headless electric bass, consider a quality adjustable strap (standard strap locks), a reliable 6.35 mm TS instrument cable, a foot tuner (pedal format) for live use, and a stable bass stand. These universal accessories are fully compatible with the M6 Headless 4.
