Tom Tone Effects is a boutique guitar and bass effects pedal builder based in São Paulo, Brazil, founded by Wellington Sato. The company started from Sato's frustration with the high cost and limited availability of boutique pedals in Brazil, and an early hobbyist habit of building pedals for his own use eventually grew into a custom shop operation aimed at producing world-class tones at prices accessible to Brazilian musicians.

The lineup spans overdrive, distortion, fuzz, boost, modulation, ambience, preamp emulator, and bass-specific circuits, alongside power supplies, accessories, and custom pedalboards. Notable models include the Six String (a Dumble-style overdrive), the Green Tea and Sakura transparent overdrives, the Jubilee dual-channel drive, the Foxxoct fuzz, and the Tom Bender MK1 fuzz. The brand also produces Carlos Santana tribute drives such as the Mark I King Snake and the Supernatural Overdrive.

Tom Tone operates as a small custom shop with an open-door policy for bespoke builds, treating each order as exclusive rather than mass-produced. The brand has a presence on Reverb and is one of the more visible Brazilian boutique pedal makers within the Latin American gear community.

Tom Tone Effects has 1 product cataloged on Equipboard, including Distortion Effects Pedals.
