La Forja is a handmade guitar and bass effects workshop based in Concepción, Chile, founded by Mauricio Oñate. The brand specializes in clones of classic effects circuits — many of them difficult to find on the modern market — spanning distortions, fuzzes, and modulations, with the option for customers to personalize both the sonic behavior and the aesthetic finish of each unit.

Pedals are built one at a time and typically feature true-bypass switching and acid-etched enclosure artwork. Examples of the catalog include a six-stage clone of the Maestro Stage Phaser and the Otaku Ratto fuzz/distortion. La Forja sells direct to musicians and ships internationally, with much of its visibility coming through Instagram and Reverb listings rather than a large dealer network.

La Forja has 2 products cataloged on Equipboard, including Overdrive Effects Pedals and Delay Effects Pedals.
