Brutal and Versatile Distortion

The Keeley Filaments is a true powerhouse for any metal musician. From the moment we unboxed it, the pedal felt robust and well-crafted, with a weight that suggested durability. Keeley really did crush it with this one in terms of build quality.

The pedal's controls are straightforward yet extensive, offering a wide range of tonal options. You get six knobs: Gain, Level, Presence, Bass, Treble, and Boost, along with two switches for Bright and Crunch. The tone shaping on this pedal is excellent—allowing us to dial in everything from tight, chugging rhythms to searing lead tones. However, we did find ourselves wishing for a dedicated 'Mids' knob to fine-tune our sound even further.

Sound-wise, the Keeley Filaments delivers in spades. It has a very clean sound, and the distortion range is wide and versatile. Whether you're playing rhythm or leads, this pedal can adapt. It is absolutely BRUTAL when you crank it up, easily one of the best high-gain pedals we've tried. That said, some might find the tone a bit dry and barky at times, which could be a turn-off depending on your style.

One downside we noted is the lack of a 9V battery compartment. While not a dealbreaker, it does mean you'll need to rely on an external power source. Also, at around $200, it’s not the cheapest option out there, but we believe it’s worth every penny for the sound and build quality you get.

Bottom line, the Keeley Filaments is highly recommended for metal musicians looking for a versatile and powerful distortion pedal. If you play hard rock or metal, you’ll likely find it worth every cent. However, if you’re looking for more mid-range control or prefer a subtler tone, this might not be your ideal match.
