MXR M-108 Ten Band EQ:
–    12db of serious cut or boost
–    hardwire bypass
–    input gain and output volume sliders
–    gain and volume slider LEDs blink to indicate signal clipping
–    illuminated sliders for onstage carving
–    glow-in-the-dark graphics
–    18-volt operation for twice the headroom of most eq pedals
–    indestructible, die-cast zinc housing

In this segment of MXR In-Depth, we take closer look at the M-108 MXR Ten Band EQ pedal. Guitar and Bass players alike revere this under-appreciated utilitarian pedal; it’s a staple in every musician’s toolbox. Everyone uses an EQ of some sort, whether it’s in their amp, mixer, or pedal board. The reason? Control. That is what the Ten Band EQ pedal is all about. Want to custom tailor your tone? Adjust for room acoustics? Give yourself a distinctive sounding boost to your solos? The Ten Band EQ provides quick, easy and precise control over ten frequencies to adjust your tone, with volume and gain options to adjust your level.

How it works:
There are ten EQ sliders for a wide range of tonal control selected at the most musical frequency centers. You can individually cut or boost each frequency to shape your tone. With + or – 12db you can get 4x the output or 4x the reduction at the selected frequency. In addition to the EQ sliders, there is a gain slider that controls the signal level going into the pedal, and a volume slider that controls the overall effect volume for ultimate control of your signal. All sliders feature a glowing LED, which will blink if the signal is clipping.

How to use it:
The Ten Band EQ is very easy to use, as the sliders are a graphic representation of the pedal’s frequency response. Here are a few settings to help you get on your way, but the best way to use this pedal is to keep experimenting and tweaking until you find your own unique sound.

    And Zay – The Moment I Feared uses it too

  • oguzhan demir

    its a perfect pedal. my friend used to have m-108 but now he sold. i am tried and its wonderful pedal. my advice is you must be sell this 🙂

  • Jonathan Malugin

    Listening to the sound samples, the metal sound was great but the clean sound had a high end snarl like an extra frequency was comming through that wasnt sussposed to be there. Maybe a setting issue I dont know, Ive never used one. I never liked the sound that come through a graffic EQ. They seem to work great on PA systems. I play Guitar and Bass but I prefer other types of EQ’s. But hey I have some Dunlop pedals and other products from Dunlop and MXR and love them. Would like to try one out sometime though to see if it would make an improvement in my sound.

    I have one of these and really like it. I have a Boogie Mark IIB and was experimenting with a DIY tube screamer to give it more sounds. I was endlessly tweeking the circuitry of the tube sceamer (changing the diodes and capacitors) and finally realized I was only using it as a clean boost to drive the front end of the amp harder. All my tweaking was trying to find the right frequency spectrum. Once this dawned on me, I went with the M108 and it works perfect to push the amp further into natural overdrive when I punch it in. In the end I have my amp set up with a nice clean channel, a nice raw distortion lead channel and then I kick the M108 in to get a smooth higher gain sound. I have the sliders fairly fat with the 2K down a little which smooths out the harsh highs. I also have the 500Hz up a little which I’ve found is that nice Wah frequnecy,which adds some nice harmonics. I then have the gain and volume up ~4 dB to get the boost. Overall, I get a very warm, smooth, and natural tube overdrive with some nice rich harmonics out of my amp using this pedal. I’d highly recommend trying this if you have a good sounding tube amp as it will add another channel. It’s quiet, clean, and does what it’s suppose to do without adding anything its not intended.

  • François

    It has 3 more bands for boosting or cutting than the boss EQ pedal; the fact it runs on 18 volts probably has an impact on its sound quality. I think I could use it not just as an effects box, but as a small, compact preamp.

    I’m getting my hands on one off those, definitely!

  • don ivey

    i bought the mxr108 eq but sent it back and got a boss eq….
    i loved everything about the eq except when i turned it on and off it would pop in the mesa booguie tube amp that i own..

  • Your.face

    That’s why your amp is the last thing you turn on and the first you turn off.

  • I consider, that you are mistaken. I suggest it to discuss. Write to me in PM, we will talk.
    It does not approach me. There are other variants?
    I congratulate, very good idea
    It is simply matchless topic
    What necessary words… super, a remarkable phrase

  • Richard

    I’m having mixed results trying to warm up my nasal trebles, particularly in the lower position of my B string. I play jazz and like a warm, bassy sound. Any suggestions?

  • Nikodiakos

    hi i would like to ask a question about the mxr m 108 settings for a violin.. Can anyone help me and suggest me which setting from the above i must use? thanks

    • John2jac

      Is Dunlap MXR listening to these responces? EQs are often used by jazz arch top players violin players bass players accoustic players, we are not all mettle players. Im not criticizing mettle, but some of us do other things. how about designing and marketing to the rest of us?

    • rocketcity

      Try the “M” shape for the sliders and tweak to your personal tastes. Should work well for violin.

  • Roberthickman123

    more than 3/4 of this demo is not targeting what the majority of buyers are going to use it for! dunlop needs to rethink its marketing strategy.

    • MXRLover

      Well said. None of the before effect : with effect samples are valid, and this guy’s affectation is more annoying arrogant ego than helpful features of the pedals. MXR should look at the far more successful factual marketing of other manufacturers. Don’t get me wrong, I love MXR pedals. I’ve been using them since 1976. It is jut sad to see their strong products getting short sold by this guy and whomever writes his lame spiel.

  • Jimmyjazzbass

    I wish they would demo with a bass too

  • Reg

    I’m getting one from do i have to buy the adapter separately or is it included?

  • Acuestickguitar

    Great comments.  I play acoustic guitar, and this is one of the best EQ pedals around.  I have to say that I the “18 volt double headroom” claim may have some truth scientifically, but it’s not very a big deal artistically.  That said, I find it very musical, and it looks really cool.  As an acoustic player, I find it lacking in two aspects:  (1) it needs a built in DI, and (2) it needs two parametric bands to sufficiently meet all EQ needs.  In conclusion, and again, as an acoustic guitarist, it give it a 7 of 10.  I recommend the Equinox by DTar as a better alternative if you don’t mind lugging around a big, although light and flimsy, EQ around, that uses a unique power source with it’s output set at 16 volts / 600 mA (who does that??).  Pro and cons . . . 

  • Dave Jordan

    Can you suggest a setting to achieve the most realistic sound of the acoustic guitar for me to start with?  I have the MXR 108 10 band EQ.  I play a Taylor 414 CE acoustic electric through a Fishman Artist 125 watt acoustical amplifier.  I have played for years with just a mike going into the PA System of the host auditorium.  Any suggestions?

    • rocketcity

      See my above post about the “M” shape. This is a classic equalizer setting with cut mids and a boost in mid bass and mid highs. In a band mix you may want to boost mids slightly to cut through a mix.

  • Leonardpaul1972

    Hi !
    How much current (in mA) does the MXR M108 need ?


    • Mark Logan


      • Jim

        why does it come with a dunlop cb-004 adapter that delivers up to 1000 mA ?

  • rocketcity

    I have had luck with the “M” shape (sliders in the form of an M) for acoustic instruments and adding a warmth and fullness to my strat. Then tweak from there. This peddle is a must have for any serious guitarist. I am running it through the FX loop on my Rivera Sedona Lite.

  • somedude9000

    To my knowledge Randy Rhoads also used this. He’s definitely noteworthy and I feel like he should be added to the artist list.

  • Excellent box. Don’t know how I played all these years without one.

  • stasko

    is the 18 V transformer included or i have to buy one ?
    is it also working with 2 9 V batteries ?
    the manual says nothing
