Shigemori is a handmade effects pedal maker based in Nagoya, Aichi, Japan, operated by SHIGEMORI emtec Co., Ltd. The company builds boutique overdrive, distortion, fuzz, and bass pedals around the stated goal of enhancing a player's tone without masking the inherent character of the instrument and amplifier. Enclosures are typically housed in machined aluminum cases, and production tends to arrive in small batches rather than large runs, giving the brand a collectible reputation in the Japanese boutique scene.

Its catalog centers on the Ruby Stone overdrive — the brand's most recognized pedal, known for dynamic, musical breakup — alongside the Muse, a lower-gain overdrive with added bass control; the Peach Puff fuzz; the Stone Drive overdrive and its custom variants; the Pretone tone processor; the RaD distortion; and the G.O.T bass drive and Tracks bass preamp aimed at bassists.

Shigemori has a following among Japanese rock and alternative players, with an artist roster that includes Toru Kitajima (Ling Tosite Sigure), members of THE NOVEMBERS, and BOH (BABYMETAL), along with international users such as Bruce Kulick (KISS, Grand Funk Railroad), John Corabi (Mötley Crüe, The Dead Daisies), and Mike Keneally (Joe Satriani, Steve Vai).

Shigemori has 6 products cataloged on Equipboard, including Overdrive Effects Pedals, Equalizer Effects Pedals, and Bass Effects Pedals. Their gear is featured by 7 artists, with the strongest followings in Rock, Pop, and Jazz. Notable users include Miyoko Nakamura, Toru Kitajima, and Yusuke (Lynch).
