FX, or effects, are guitar pedals and processors used to shape, enhance, or completely transform your sound. They can add anything from subtle colour and warmth to dramatic textures, ambience, and movement, allowing players to craft a tone that suits their style, genre, and playing approach.

Whether used individually or chained together, FX pedals give control over dynamics, distortion, modulation, delay, reverb, and more. From simple analogue designs to advanced digital units, effects are a core part of modern guitar setups, helping players create distinctive and expressive sounds.
