The MI Audio Crunch Box Distortion Guitar Effects Pedal brings you high-gain British amp distortion in a stompbox. MI Audio did a careful study of the way that modern British style amps get their overdrive and found that there was a very big concentration of the frequency information in the midrange. The Crunch Box distortion pedal captures the huge crunch of a Marshall amp on steroids and has become one of MI Effects most popular pedals. The Crunch Box is of the fastest selling boutique distortion pedals in the world.

Simple and straightforward, with just gain, tone, volume and an internal presence control, the Crunch Box is based on a multiple clipping architecture (the signal is clipped 3 times. In the lower gain range, the pedal's tone is very punchy and throaty. There are some great classic rock rhythm sounds to be found in there. As the gain is wound up, the Crunch Box develops a beautiful singing lead tone. Pinch harmonics are a breeze. The tone control has a wide sweep with a lot of top end. I have put in there more gain than anyone should need, but due to the way I handled the pre-overdrive tone shaping, the pedal always stays tight and each pickup retains its character, including single coils. The Crunch Box has a lot of volume up its sleeve. You will find though that 12 O'clock is close to 'neutral'.

An Internal Presence Control helps control the 'shape' of the pedal. By winding up the presence control, the lows won't feel as powerful, which some people might find to be a bit too much. Also, this creates the effect of giving the pedal even more top end. So with the new Crunch Box, there is no chance that the pedal will be too dark. The Internal Presence Control is very useful if you wish to match the Crunch Box to your amp because some amps can be a lot brighter/darker than others.


  • High Gain British Distortion at its best
  • 3 external and one internal control
  • Gain – from the lightest breakup to insane high gain scream
  • Tone – custom taper control which adjusts the high end cut of the pedal.
  • Volume – tapered for a more gradual and controlled volume sweep.
  • Internal Presence control - for adjusting the 'shape' of the Crunch Box's sonic footprint.
  • Professionally powder-coated and silk-screened enclosure, measuring only 4.3" * 2.2"
  • Heavy Duty 3PDT footswitch with True Bypass
  • 9V Battery or DC power supply with up to 25V headroom

Pound for Pound the best!

By Laven

from Aurora, Colorado

I have owned this pedal for 3 months and every day I become more impressed with it. From slightly overdriven blues to AC/DC this pedal nails it. If Metal is your thing this is probably not the best pedal for you. Over the past couple of years this economy has forced me to sell some high end equipment and currently I play through a cheap solid state amp with my MI Crunch Box and an anolog delay. I know many won't believe me but I don't feel like I've given up anything. The MI Crunch Box is dynamically sensitive to pick attack and responds very well to my guitars volume level. This pedal behaves and sounds very much like an all tube Marshall amp at a fraction of the cost. For the price, this box is a steal and in my opinion one of the best values out there. And by the way it's built like a tank. Buy it!!!

Thick, Crunchy Overdrive

By Eric

from Michigan

This is called a distortion pedal, but is actually more of an overdrive pedal on steroids! I have a blues jr. and the pedal does a nice job of giving a warm, crunch overdrive through a small amp. With the gain controls, you can adjust from bluesy overdrive to a Marshall crunch. It also has an internal presence control so that you can adjust it to your amp. I was looking for a pedal that could do classic rock ala ACDC. This pedal fits the bill. On a side note, IMO it sounds a bit better with humbuckers for whatever reason, but still is ok for single coils.

Great Pedal

By Jarrett Anderson

from Napa, Ca

I play a Fender American Standard Ash Strat with single coil set up through a Blues Jr; a very clean set up. I searched high and low for that British crunch tone for some music I was working on, with out buying a Les Paul with a Marshal stack. I found what I was looking for in this pedal. This is a very versatile pedal that you can use as a clean OD or role on the gain for some big distortion.

Get the CrunchBox! Sure won't let you down

By Boselli

from Montevideo

Far from a shy discrete overdrive, this little and simple red devil will give you an incredibly powerful distortion with very rich tone possibilities. Pushing the gain you will get as much sustain as you need as well as the most beatiful harmonics and feedbacks. My set: Gibson Les Paul Studio through a Fender Hot Rod DeVille. It also works fine at low gain levels and, as it's a pretty loud pedal, you may use it as a booster for soloing or chaotic noisy parts. The only bad thing I have to say about the CrunchBox is that it's a bit noisy when activated (noise/signal relationship). If I lose it, I'd purchase it again.

As Good or Better

By Butch S. on the MI Audio Crunch Box

from Now Little Rock--New Orleans for 99.5% of my life.

I own a bunch of these sort of pedals and the C.Box by MI Audio stands-up against any one of them and maybe even Better depending on what you want. I Love my OCD pedal but then there may be a time when my Crunch Box is absolutely necessary.

what a difference


from St. Cloud, Fl

Not my first pedal- but so far my best. Sure not everyone is supposed to do the same thing, but this one will have the most "affect" on your playing. Sure- different guitars will be a part of your styles--but this pedal will save the intermediate player from needing just another guitar and will enhance every other style/skill level. It is so light-weight - you'd think it was a toy, which just goes to show that the hype over "heavy- built to last" doesnt mean better-- great materials and quality come in all sizes and weights. This is an outstanding purchase.

Easy to use, exceptional tonal variety and smooth, rich warmth. Allows me to play anything from thrash metal to slightly over driven blues.
