Sire's Modern Headless Bass: Lightweight, Versatile, and Built for Tone

Coming from the series of Sire modern basses is another contemporary bass, the new M6 Headless. It is designed distinctively compared to previous Sire models, weighing less than 8 lbs (based on the 4-string variant) to prevent players from experiencing neck-dive and ensure enhanced comfort and balance in playing. Based on our 4-string samples, the weights are 7 lbs 1 oz, 7 lbs 10 oz, 6 lbs 12 oz, and 7 lbs 8 oz. Equipped with a preamplifier and various switches, it is a highly versatile bass, catering to genres such as pop, rock, metal, blues, and more. The M6 Headless has 24 frets and is available in 4, 5, and 6-string variants. It comes with Sire official gig bag.

M6 CONTROL LAYOUT

1. Volume

Controls the overall output. Turn toward Open to increase volume and toward Close to decrease it. Fully closed mutes the sound.

2. Master Tone

Adjusts brightness. Turn toward Open for a brighter tone and toward Close for a darker tone.

3. Pickup Balancer

The center position uses both pickups equally. Turn toward Neck for a warmer neck pickup sound or toward Bridge for a brighter bridge pickup sound.

4. EQ Controls

The Treble, Middle, Middle Frequency, and Bass controls work in Active Mode.

5. Treble

Boosts or cuts the high-frequency range.

6. Middle

Boosts or cuts the midrange.

7. Middle Frequency

Selects the mid-frequency range affected by the Middle control.

8. Bass

Boosts or cuts the low-frequency range.

9. Active / Passive Switch

Select Active to use the onboard preamp and EQ. Select Passive to bypass the preamp for a more natural passive sound.

10. Pickup Mode Switches

Choose between three pickup wiring modes:
• Parallel Humbucker – clear and balanced.
• Single Coil / Outer Coil – brighter and more focused.
• Series Humbucker – stronger, fuller, and higher output.

Basic Tone Tips

For a balanced sound, keep the Pickup Balancer and EQ controls near the center position.
For a brighter, tighter tone, blend toward the bridge pickup and slightly boost Treble.
For a warmer, fuller tone, blend toward the neck pickup and slightly boost Bass.
For more detailed tone shaping, adjust the Middle Frequency first, then boost or cut with the Middle control.
