SP Luthier Notes: This instrument has been carefully inspected and, if necessary, serviced by our certified luthier to ensure it is in excellent playing condition.

Step into high-end lutherie royalty with the extraordinary Ken Smith BSR-4 FL! Renowned worldwide for setting the gold standard in boutique bass crafting, this fretless masterpiece features striking flame walnut top and back wings wrapping a carved figured maple body core, paired with a rock-solid 5-piece maple and shedua neck. Its dark Macassar ebony fretless fingerboard offers a silky, unhindered surface, delivering singing "mwah," deep low-end resonance, and incredible tactile response across a 34" scale. Powered by signature Ken Smith humbucking soapbar pickups and slick black hardware, this 8 lb 14 oz instrument yields exceptional punch, articulate midrange detail, and studio-ready clarity. Complete with its original hardshell case, it represents the absolute pinnacle of fretless tone and visual elegance.
