Grobert Effects is a Polish boutique pedal builder founded by Łukasz Grobert in 2013. The company specializes in handmade analog effects, with a particular focus on faithful recreations and reissues of legendary, hard-to-find vintage pedals — often with added features and modern refinements.

The lineup includes pedals such as The One Chorus, an analog chorus modeled after the 1976 Boss CE-1, and the Golden Legend, an overdrive/boost inspired by the Klon Centaur. Pedals are sold direct through the brand's website as well as through retailers including Reverb, Guitar Center, and a network of specialty dealers in Europe and North America.

Grobert Effects has 9 products cataloged on Equipboard, including Overdrive Effects Pedals, Chorus Effects Pedals, and Noise Gate Effects Pedals.
