Honda Sound Works (HSW) is a Japanese boutique effects builder based in Tokyo, founded by Hiroyuki Honda. The shop is known for handmade, small-batch pedals produced in very limited runs, many of which have become collectors' items on the secondary market. Its catalog leans heavily into overdrive and fuzz, with models such as the Fujiyama Drive, Fab Drive, Drive-F, Crazy Fuzz, Mad Fuzz, ISO Fuzz, Boosterman, and the Lenny overdrive, alongside the Fab Delay, Spice, Genma, and the RVW-390 wah.

Beyond stompboxes, Honda has collaborated with Japanese luthiers including Tokai and T.S Factory on guitars carrying the HSW name, and operates a related amplifier line, FEE (Far East Electric), whose Phoenix series covers a range of EL34-based British-voiced designs. The pedals are typically hand-wired with attention to vintage-style circuits, often using germanium transistors on the fuzz models.

Honda Sound Works has 3 products cataloged on Equipboard, including Overdrive Effects Pedals, Delay Effects Pedals, and Fuzz Effects Pedals. Their gear is featured by 3 artists, with the strongest followings in Rock and Jazz. Notable users include Toru Kitajima, Michio Kurihara, and Adam Rogers.
