320design is a boutique guitar effects pedal manufacturer based in Chiyoda-ku, Tokyo, Japan. The company was founded by a graphic designer working alongside staff from an instrument development division, and this blend of visual design sensibility and engineering expertise defines the brand's identity. Known for their distinctive tall-box enclosures and eye-catching aesthetics, 320design produces a small but focused lineup of handmade pedals, including the Brown Feather distortion, the Landmighty multi-function overdrive, the Sunakake overdrive/booster, and the Canary Drive overdrive.

320design has built a reputation for high-quality boutique craftsmanship and creative collaborations that bridge Japanese pop culture and guitar gear. The NITROGIC-01, a signature distortion pedal developed with HISASHI of the rock band GLAY, extends the Brown Feather circuit with added boost functionality. The brand has also produced officially licensed pedals tied to anime franchises, including the K-ON! signature pedal series (featuring character-themed drivers like the Azusa Driver and Mio Driver) and a JoJo's Bizarre Adventure: Stone Ocean collaboration that yielded the Strung Fuzz pedal along with themed picks and straps. Distribution remains limited, with only a handful of dealers in Japan, Australia, France, and Hong Kong, making 320design pedals sought-after items among collectors and boutique gear enthusiasts.

320design has 3 products cataloged on Equipboard, including Overdrive Effects Pedals and Distortion Effects Pedals.
