MXR

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
