This unassuming little box shovels out enough low frequencies to scare a blue whale.

The MXR Blue Box takes your guitar signal, fuzzes it up, then duplicates it 2 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!

Here are just some of the people who are using this box: John 5 - Rob Zombie; Mick Thompson - Slipknot; Munky - Korn; Jimmy Page; Tim Skold - Marilyn Manson; Jay Baumgardner - Producer Zakk Wylde; Geordie White - A Perfect Circle.

MXR M-103 Blue Box Features:

  • Power: Single 9 volt battery or Dunlop ECB-003 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

  • Adds personality to your sound

    As reviewed by Leo on 1/20/2010

    Great effect, with this pedal you're gonna be recognized and remembered everywhere you'd been. Me, I use in most of my songs when playing some intros and licks, and people come ask me how did I make my guitar sound as deep.. Use the blend knob at 3 o' clock position, and how it sounds with that fuzz 2 octaves down!

  • It does what it does

    As reviewed by Mike W on 6/29/2011

    Listen to Jimmy Page's solo on Led Zeppelin, Fool in the Rain, if you want to know what this thing does. It's a one trick pony but it is a unique arrow in any guitarist quiver. It's part of my "toolbox." I've used it with good results on a few tunes in the studio. It does what it's suppose to do. Is it "good?" Well, like I said, listen to Page's solo. If that's what you want, that's what you'll get.

    Well made unit simple. I would only recomend this pedal to those who want a little something extra to throw in the mix once in a while . It is probably not the most used effect on my board but it has a place .
