The MXR Blue Box is a buzzing fuzz and octave pedal that is unmistakable and unapologetic. Creating a completely unique sound, the Blue Box utilizes a mix of a buzzing sub-octave effect and gated fuzz effect that share a single blend knob. The control knob can be used to dial in to isolate either effect or dial in a mix between the two, making for a pedal that is more flexible and customizable than seen at first glance. With a sub octave voice that borders on a synth sound, the MXR Blue Box can tune into an 8-bit effect that is compatible with glitchy, synth-heavy sounds. The MXR Blue Box is a unique and fuzzy stompbox with a voice reminiscent of synthetic, digital buzzes of decades before to suit the needs of the modern player.
- Fuzz and octave combination effect pedal
- Responsive Output and Blend controls
- Aggressive fuzz tones to 8-bit buzzes
