Product Description

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! Powered by a single 9 volt battery or Dunlop's ECB-03 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.

Customer Reviews
4 out of 5 (27 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Nice, with a small mod..."
Overall: I liked the sound, but the volume drop from engaging the pedal is ridiculous. There's a simple way around this: clip the C11 capacitor off. Voila, gain is back! The tone is more aggressive (the cap is a low-pass filter, I believe) but this is not necessarily a bad thing - and if you're handy with a soldering iron you can always change the value to something less extreme, and/or put it on a switch so you can go back if you want to. It's a waaacky sound, once you get it dialed in. Pretty simple - one knob is level, the other is amount of fuzz vs. low-octave mixed in. All the way CW it's a nasty fuzz pedal, all the way CCW it's fat, fuzzy, synth-bass. Mix to taste. There are probably better (or at least different) pedals like this out there, but at this price point I'm betting this is the one.
Style of Music: Rock, funk, blues, experimental...whatever.

MXR M103 Blue Box Customer Review
Sound: The sound is really juicy, but it takes a lot of effort to get the sound you want, and it is not always possible too. Ease of Use: I know that it was created to be a little bit unpredictable, but id use it more often if i could get from this box what i want every time.
Style of Music: psychodelic rock/funk/electonic

1. zZounds offers the industry‘s most musician-friendly payment plans

zZounds offers a variety of Play as You Pay installment plans that allow you to get the gear you want today. While our competitors might offer house credit cards that require you to fill out an application and pass a credit check, our payment plans are easy to get, simple to use, and, best of all, accrue zero interest. Unlike those house credit cards that can leave you vulnerable to exorbitant interest charges once the promotional period ends, we never have and never will charge interest when you take advantage of one of the zZounds Play as You Pay plans.
