Nemphasis is an Italian manufacturer of handcrafted effect pedals, preamps and pedalboard power supplies for guitar and bass, based in Calvisano in the province of Brescia. The company was established in 2011 and builds its products around analog circuitry, using the tagline "Life is Analog" to underline its focus on tone preservation through the signal chain.

Its catalog spans overdrives, distortions, boosters, compressors, modulation and bass-specific tools, including the X7 Tube Overdrive (built around a 12AX7 valve), the Silver Box booster and EQ, The Muff distortion, and the O2 Oxygen and Pro Oxygen bass preamps. Power and routing accessories sit alongside the pedals, with the Oktopus, Tentacles and Snake AC isolated power supplies and the PB-8 MIDI-capable foot controller rounding out the line.

The brand presents itself as a small-batch boutique operation rooted in Italian craftsmanship, with units assembled and tested in-house. Reviews in outlets such as MusicRadar and Guitar Interactive Magazine have covered models including the Silver Box and the Oxygen series, giving the brand visibility outside the Italian market.

Nemphasis has 3 products cataloged on Equipboard, including Compressor Effects Pedals, Overdrive Effects Pedals, and Bass Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock and Blues. Notable users include Chris Buck.
