Leduc is a French guitar and bass workshop founded by luthier Christophe Leduc, who built his first instrument in 1973 and has produced handcrafted guitars under his name since 1978. The shop is based in Boulange, in the Lorraine region of northeastern France, and focuses on high-end electric guitars and basses, with some acoustic work.

The brand is best known for its U-Bass and U-Guitar models, which use a free-floating soundboard and asymmetrical bridge — a design Leduc patented in France in 1989 and granted an international patent in 1991. The intent of the floating soundboard is to let an electric instrument's body respond more like the resonant top of an acoustic. Other lines include the Masterpiece series, built around a neck-through-body design typically pairing maple and bubinga, and the PAD basses, which use Padauk wood throughout the neck, fingerboard, and body for tonal consistency. Basses are offered in four-, five-, and six-string variants, with custom-shop options available.

Players associated with Leduc instruments include bassists Abraham Laboriel, Marcus Miller, Frédéric Monino, and André Manga.

LeDuc has 2 products cataloged on Equipboard, including Solid Body Electric Guitars.
