The Sire Series 6: The Modernized "Jazz" Spirit, 2025 Edition
The V6-4 FL belongs to the 2025 generation of Sire Series 6 basses, a "J-type" lineage designed to offer smooth playability, refined finish, and modern versatility. The satin finish highlights the grain of the solid ash top, while the whole retains the Sire sonic DNA that has won over many bassists, both on stage and in the studio.
Who is it for and which styles?
This 4-string fretless bass is primarily aimed at intermediate and expert players who want to work on intonation, vibrato, and legato, with an immediate response under the fingers. It excels in jazz, soul, R&B, funk, pop, and contemporary music, wherever right-hand nuance, round attacks, and "singing" phrasing make the difference.
The Sound
The combination of a mahogany body and solid ash top emphasizes full, round lows while maintaining defined upper mids to bring out the articulation of a fretless. The Marcus Super-J Revolution pickups (J-type configuration) provide clarity, attack, and a vintage-inspired tone with precise note reading. The Marcus Heritage-3 preamp with its 3-band EQ (fixed mid frequency) allows quick shaping of presence and balance in a mix, and the push/pull gives instant access to passive mode for a more direct and organic approach. The 34" / 864 mm scale length ensures tension, sustain, and stability, while the bone nut and Modern-S bridge contribute to a clear attack and consistent note hold.
Recommended Compatible Accessories
For this long scale bass, favor a 4-string long scale 34" bass string set. On a maple fretless fingerboard, flatwound or tapewound strings are particularly appreciated for their smooth feel and warm tone. A comfortable strap is also an excellent addition to optimize ergonomics during rehearsals and concerts.
