Product Description

This is the crazy effect heard on Jimmy Page's "Fool in the Rain" solo. The Blue Box Octave Fuzz 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 fuzz tone is mixed with the two octaves down signal. Not for the timid—there is truly nothing like the Blue Box.


From the manufacturer

MXR is a New York-based manufacturer of effects pedals from Rochester. The manufacturer was co-founded in 1972 by Keith Barr and Terry Sherwood and incorporated as MXR Innovations, Inc. in 1974. The MXR is now owned by Jim Dunlop, which continues to produce the original effects units along with new additions to the line.

AI-generated from the text of customer reviews

15 customers mention8 positive7 negative

Customers are mixed about the sound quality of the guitar effect device. Some mention it sounds amazing, interesting, and deep. However, others say that there is a significant volume suck when the pedal is activated, and the 2nd octave signal has a very bad sound.

"The sound is deep and can make your guitar sound like an old school computer game from the 80's...." Read more

"...There is a significant volume suck when the pedal is activated, and for its effects to work properly, you have to have some volume behind it to work..." Read more

"...It's mostly monophonic so don't expect to be strumming chords with this thing on unless you're into weird sounds (which I totally am so I do)...." Read more

"Sounds amazing, got it as part of my Jimmy Page inspired pedalboard so I can get the tone from the solo in the song Fool In The Rain...." Read more

9 customers mention4 positive5 negative

Customers are mixed about the performance of the guitar effect device. Some mention it's a great pedal, really fun, and awesome, while others say that it'd be better off buying a new one. Some say the fuzz is pretty lame, and the pedal doesn't work upon arrival.

"...Too much feedback, and it sucks all your volume.The fuzz is also pretty lame.. Also not polytonal...." Read more

"This is a very very narrowly used effect. But, it's so awesome. Let's face it, this is a novelty...." Read more

"Weird synthy pedal. Unpredictable tracking sometimes- not for chords. Minimal controls, so may take some dialing in...." Read more

"...A really fun pedal to mess around with since you can get some crazy 8-bit like sounds out of it but part of its range has a nice dark, heavy..." Read more

Interesting but underrated effect.

Nice octafuzz effect used by Jimmy Page in "Fool in the Rain". I'm using it on the cover of "Helter Skelter".
