MGR/Jared's review"Line 6 DM4 Distortion Modeler"

Line 6 DM4
I bought it for $200 used at Guitar Center, but was in perfect condition. I bought it because I had read good reviews on it, and needed some new sounds for my playing.

I like how there are 4 available presets, and 16 different distortion settings. It's easy to preset, and the sound and quality of this unit is amazing. I play everything from punk, to rockabilly, and this has all the sounds I need to play them.

The gold-yellow color.

This is a top quality stomp box, it's built extremely well. It's gotten kicked and hit with the vacuum, but it takes a licking and sounds like new. The sound is impeccable, and it's sturdy and loud enough to last through your gigs.

Alright, this is the best distortion pedal I've ever played and I have played a lot. This is top quality manufacturing and great sound for an even better price. With sounds modeling effects such as Tube Driver, Rat, Tube Screamer, Big Muff, Fuzz Face, etc., you can't go wrong.

MGR/Matt's review"Line 6 Dm4 Distortion Modeler"

Line 6 DM4
I paid $250 for this pedal. I am usually opposed to buying and dislike multi-fx processers, but I knew that this one was different. I was originally going to buy a Marshall blues pedal and another Boss single effect pedal, but I fell in love with this as soon as I played it. I paid $250 for the pedal, $20 for the power supply, and $50 for the expression pedal.

I like this unit because it fit the kinds of music I played (mostly Jimi Hendrix and Led Zeppelin and a bunch of older stuff). I like this because there is pretty much a distortion type for every band and song you can imagine. You can also adjust the levels of drive, volume, and more to each of the types. If you want a clean sound, you can still use this pedal. There is a clean sound, so you adjust the settings, and you can use the expression pedal as a volume pedal.

What I dislike is that you can't really switch the types while performing. I mean you can, and I suppose you can maneuver your foot, put it really is a pain to turn the little dial. I guess if you're not wearing shoes, it would be easier, but I just use my fingers to change it. This really can get crazy when you're playing live though.

This is a solid unit. The construction is very good. I treat my pedal with lots of care, but I suppose it could withstand a lot. I never dropped it, but I'm sure it would be fine. I've never had a problem with this. The finish is really nice (gold) and I wouldn't trade this thing in for anything. This almost looks as sharp as it plays.

I think this is a great unit. I would definately buy another if I lost this. This helps me cover basically anything I want or write cirtually whatever I want. The dials for each sound type will let you cover basically any sound. These endless amounts of sounds mean that any sound can be imitated or created. The expression pedal can be used to warp between sounds, and sometimes I even use it as a volume pedal. The power supply means I don't constantly burn through batteries; trust me, I use this A LOT.

Bottom Line- I love my pedal. Cheers to Line 6!

MGR/Anonymous's review"Line 6 DM4 Distortion Modeler"

Line 6 DM4
$225 off of Ebay. I bought this box as it purported to model a whole slew of vintage and not so vintage distortion and overdrive pedals. I also wanted the capability of having more than one distortion/gain effect available on a footpedal, and this pedal allows 3 presets to be selected with the click of a switch.

Very heavy duty, very realistic modeling of the vintage pedals (and I've had a lot of them). Easy to set-up and use, easy to program up to 3 presets on the footpedal. Wide variety of tones/settings to choose from.

The color...yucky gold-yellow.

Very heavy duty switches and case, somewhat flimsy cord from external power supply that plugs into the unit. They would have been better off with a permanent AC cord.

This is a great pedal if you want to use 3 distortion/overdrive settings available via the press of a footswitch. The large variety of tone/gain settings make it easy to select which ones you want to save to the footswitches (3 at a time). I got rid of all my other distortion pedals and kept this one. I like it a lot.

The Line 6 MM4 is an overdrive modeling pedal that contains 16 different types of overdrives that are modeled after classic pedals and sounds. It has 1/4 inch inputs and outputs as well as a 1/4 inch output for the optional expression pedal. It runs on batteries or with the optional power supply that can also power any of the pedals in this line of Line 6 effects. It is not a rackable unit as it is a stomp box.


The configuration of the Line 6 MM4 is pretty easy to understand, and is very similar to the other pedals Line 6 makes in this line like the DL4 and the FM4. All the way to the left there is a switchable knob to choose between the different types of overdrive and then there are five other knobs that control various parameters depending on which overdrive you have selected. There are also four switches that are each programmable with your own custom sounds, which comes in extremely handy for live shows. The manual for the Line 6 MM4 is extremely well laid out and if you are new to pedals like this it might be a good idea to have it around. However, it is pretty easy to use and I never had a real use for it.


The sound quality of the Line 6 MM4 isn't up to par when compared to some of the other modeling pedals that Line 6 has made in my opinion. It is pretty hard to get this many realistic sounding overdrives and distortions within the same pedal, and while there are some good sounding overdrives on this, to me a lot of them are not that usable. It is great to have so many different sounds within one unit, but I'm not a huge fan of a few of the choice on this pedal. All in all, there are some nice sounds on this pedal and it is a good choice for those looking to get their feet wet a bunch of different sounds.


I've been using the Line 6 MM4 for about four years and while it isn't the best overall sounding overdrive pedal I've used, it is certainly nice to have so many different types of sounds in one place. My only complaint is that I wish there were a few more realistic sounds on this unit, but overall it is solid and is a great addition to anyone's guitar rig.
