The Keeley Filaments is a high-gain distortion pedal designed to deliver powerful, aggressive, amplifier-like tones with plenty of saturation, sustain, and articulation. It is particularly suited to hard rock and metal players who want a thick, modern distortion sound while retaining enough control to shape the response to different guitars and amplifiers.

The Filaments combines substantial gain with an active-style EQ section, allowing you to sculpt the lows, mids, and highs more extensively than with a basic distortion pedal. This makes it useful for creating everything from tight, punchy rhythm tones to saturated lead sounds with extended sustain.
