Valco FX is a Canadian boutique effects pedal manufacturer that hand-builds its products in Canada. The brand takes a modern approach to classic guitar tones, focusing on multi-function designs that pair tone-shaping utility with traditional dirt and ambience circuits.

The lineup centers on the KGB Series, including the KGB Dist and KGB Fuzz Jr, which combine distortion or fuzz circuits with a Variable Impedance Selector intended to reshape how the pedal interacts with the rest of a signal chain. The IMP Boost spins that impedance function off into a standalone boost that can be placed at the front of a chain for gain or at the end for volume. The Five-O is a 3-in-1 multi-effect housing independent Drive, Tremolo, and Reverb sections in a single enclosure, while the BloodBuzz fuzz has been offered through partnerships with shops like Eastwood Guitars and Truetone Music.

Valco FX pedals are built using rugged enclosures and higher-grade components, and the brand is distributed through specialty retailers including Electric Mojo Guitars, Truetone Music, and Reverb.

Valco FX has 4 products cataloged on Equipboard, including Multi Effects Pedals, Fuzz Effects Pedals, and Tremolo Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Matthew Followill.
