About This Listing

This unassuming little box 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 dry signal and the effect. Using it 100% wet is quite an experience, but more recognizable sounds appear as you dial In more dry signal. The Blue Box is known for having a chaotic personality that can make each session a totally unique experience!

  • Power: Single 9 volt battery or Dunlop ECB-002 AC adapter
  • Controls: Footswitch toggles effect on/bypass (red LED indicates on)
  • Output knob sets total output gain
  • Blend knob adjusts ratio of dry (clean) with wet (effects) signal

Product Overview
The MXR Blue Box became the go-to octave effect and a gear icon after Jimmy Page used it for his solo in "Fool In The Rain." It's incredibly simple - two knobs for Output and Blend - one of those pedals that just does its thing and sounds good without a ton of dialing in. It tracks your notes and doubles with a two-octave down copy, providing a bassy, raw feel. Put it front of a fuzz and stand back.
