The Keeley Filaments is a seriously cool overdrive—it nails that cranked amp vibe without the massive wattage. It’s a fantastic option for players seeking a versatile, high-gain tone, especially those into rock, blues, and even some heavier styles where you need a bit of grit and sustain. The toggle options add a surprising amount of tonal shaping.
