The Sire Swamp Ash J Bass:
- Sire's all-around flagship bass made of Swamp Ash body is now called Sire V8. It is upgraded with the Marcus Miller-favorite Sire Champ neck composed of the Edgeless™ feature and roasted hard maple material on the neck and fingerboard for a fancier feel while playing it. The Swamp Ash body and Sire Champ neck match up making the standard Sire J bass long playing-ready. Equipped with advanced pickups with a full set of EQ controls, the V8 is a machine that can deliver a clean and deep tonal palette for more personalized tones.
