The MXR M103 Blue Box effects pedal 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 effects pedal 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.
