What Electro Harmonix say.....
This is the crazy effect heard on Jimmy Page's "Fool in the Rain" solo. The Blue Box takes your guitar signal and duplicates it two octaves down for a huge, subterranean tone. The Blend knob lets you control how much of the effected tone you mix in with your dry signal. Not for the timid—there is truly nothing like the Blue Box.
Other artists using the MXR Blue Box include: Paul Weller, Black Stone Cherry and Interpol.
What Reidys think:
A great combination of octave and fuzz, this pedal helps create a unique sound, housed in a sturdy and lasting case. A fantastic addition to any pedal board!
How to use the Blue Box:
To set up the Blue Box, plug your instrument into the Input jack and your amplifier into the
Output jack. Start with the Output knob all the way up (clockwise), and the Blend knob all
the way down (counterclockwise). Turn on the effect with the footswitch toggle, making sure the red
LED is ON to indicate that the effect is active. Then gradually raise the Blend knob
to increase the amount of distorted signal mixed with your clean signal. Experiment with different
settings, stopping when the desired blend of distortion is reached.
Once your distortion is set, adjust the Output knob for the desired output volume. You can start by
toggling the footswitch on and off, and comparing the volume with and without the distortion
effect. For many playing situations, matching the two volume levels is desirable, especially if
you’ll be switching distortion in and out while playing. However, you can also use the Output knob
to BOOST the overall volume for a solo, by adjusting it so that the effected volume is louder than
the clean signal.
Part of the charm of the Blue Box is that it creates two kinds of signals…those your
amp can process and reproduce, and other tones that are completely indigestible and non-
reproducible by your amp, creating interesting distortions. Every amp and every situation are
unique, and will create different results with the Blue Box. Experiment with each new situation,
and you’ll soon learn what the M-103 is capable of.
If your guitar has multiple pickups, you may find that the Blue Box works best with the bridge
pickup favored, and the neck pickup(s) rolled off. If you find that the distorted tones are causing
too much breakup or distortion in your speakers, turn down the Blend knob to mix
in a higher ratio of clean signal; or turn down the Output knob to reduce the overall volume coming
from the unit. You can also use the Blue Box with a compressor (see M-102 Dyna Comp) to
even out the levels and protect your amp from gain peaks. When connected upstream of a compressor,
the Blue Box will deliver the most controlled tones. When connected downstream of a compressor, the
amount of compression will activate independently of the Blue Box’s output.
