Overview

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.

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
