Darta Effects is a Brazilian boutique effects pedal builder founded by Marcos Rela, who began the venture after returning to guitar and building pedals as a hobby before transitioning from a career in television post-production into full-time pedal manufacturing. The brand is based in Brazil and has become known in the country's pedal community for hand-built, customizable stompboxes where both the circuit and the enclosure artwork can be tailored to the customer's specifications.

The company's catalog covers a range of effect types including overdrives, delays, tremolos, and boosts, alongside modified takes on classic circuits and transistor-based preamp emulations such as a Marshall JCM800-style pedal. Notable models include the Mary Smoke tap tremolo and the White Rabbit tap delay, the latter recognized as one of the few domestically developed tap-tempo delay pedals in the Brazilian market. Darta is recognized for a close, informal working relationship with its clients, with many orders involving direct collaboration between Rela and the musician on circuit tweaks and visual design.

Darta Effects has 9 products cataloged on Equipboard, including Overdrive Effects Pedals, Equalizer Effects Pedals, and Delay Effects Pedals.
