The MXR M-103 Blue Box Fuzz pedal shovels out enough low frequencies to scare a blue whale. It takes your guitar signal, fuzzes it up, then duplicates it two octaves down. You control the output and the mix between the fuzz signal and the octave down effect. Use it to produce synth like bass lines, fuzz heavy guitar or any combination for massive wall of sound. The Blue Box is known for having a chaotic personality that can make each session a totally unique experience!
