Trusted musician and artist reviews for Line 6 DL4 Delay Modeler
Based on 52 Reviews

I bought this more for the looping capabilities than the delay (14 seconds of loop memory). Gotta admit, I saw Howie Day several years ago making heavy use of it and I loved the looping bits he did with it. It's just a very fun box, price isn't bad either for all you get.

Pretty awesome delay pedal & looper
The Line 6 DL4 is one of those pedals you almost have to go out and try simply because of it's popularity amongst guitarists. To be honest, I'm not much of a delay pedal snob. I haven't owned or tried enough delays to really understand the nuances. Maybe for that reason, the fact that this pedal models 16 echo and delay boxes is perfect for me. The guitar sound I really like to emulate is a Editors/Coldplay/Bloc Party sort of sound, and this pedal has plenty of options for that.
I'm a fan of looper pedals, so the onboard 14-second looper is really what sold me on this one. I saw it as a way to get a good looper and a variety of delays all in one box... at least until I build out my pedal collection and go deep on some delays. The loop function is super easy to use, and 14 seconds is plenty of time to record a substantial loop and jam on top of it - it's pretty satisfying sounding like a one man band!
The build quality is great, I've gigged with it and have had no issues. Admittedly the price is a little steep, but I've had this thing for so long and it has brought me so much enjoyment that I don't really think about what I paid for it.
I'd say an easy 4 or 4.5 stars out of 5 for the DL4. Even if you're a delay pedal purist or collector, try this one out, it might still have something to offer you.

Have you tried TC's Flashback X4? I think nowadays is a better alternative in the same price league, and I think it's not as popular as the DL4 just for the fact of the many options you have around today while the DL4 made its way a time ago when the fact of far less competition helped turning it into the classic that today it is.

I haven't tried the TC Electronics Flashback X4 - wow it looks so similar! Yeah I totally agree with you, the DL4 came out a while back and now everyone uses it. Next time I'm at the guitar store I will definitely play with the X4 and let you know what I think :)

Yeah, the X4 is very similar at first sight as it doesn't overwhelm much more about the interface (indeed, it looks/feels even easier) while in fact it covers many other advanced features (useful and inspiring), I'll be waiting for your review then!

Heaps of sounds plus a looper!
SO many different delay effects. Can bank up to 4 preset sounds. Plus a looper. Great for live and recording. Used one for years and didn't use to its full capacity. Just so many options.

Plan on getting a cubist effects standard mod on this also.

Loads of fun...
Why the shit did I sell it? No idea. It's lo-fi, it's got its limitations- but it's just endless fun! I plan to get myself another one soon as I can.

you sold it because they break so easily? Line6 invented the 4 button delay pedal but they also make the least roadworthy pedal in this style, no wonder they discontinued it in favor of those M series all in 1 pedals. The filter delay is where this guy shines... otherwise I prefer TC stuff, but I used to always find uses for the filter delay and I can't reproduce those exact sounds with ANYTHING else w/o chaining up gobs of effects or resorting to post processing with plugins.

I just miss goofing around with this guy. My tech put in all these mods & better switches. Community rules!

I've seen people add little toggles allover these.... no idea what they did. I broke mine so fast on the road that I abandoned the whole thing and went back to my Yamaha SPX90 and a rack for a time...

Can't blame ya & I never took mine on the road + mine was basically a tweaked Rolls-Royce version. That and my tech then, had the most magical & creative guy ever. He's offered tons of mods I'd never have thought of that were always fuckin' awesome.

Complete and very useful
A pedal with endless possibilities! It is very well build. Some people complain about a volumedrop or about the switches. I don't experience any problems with it. I used the regular flashback of TC Electronic, but I was missing the opportunity of presets. Especially the looper is very useful. The pedal is quite big and maybe expensive for some, but for its sound and possibilities it isn't expensive at all.

So many options and great looper!
This pedal has served me so well. I'll admit it, if i had the extra money, I would have bought myself a TimeLine a long time ago. I picked up my DL4 used quite a while ago and it has been a valuable part of my board ever since then. Although it doesn't have quite as many options as some of it's competitors (few can keep up with Strymon), it still has more effects and combinations than I have ever been able to put together and there has never been a delay lick that I haven't been able to replicate with this guy. It's also very easy to use and figure out and the controls are straight forward and logical. On top of all that the looper in it works great and gives you even more options with stop/play button, a "play once" button, and even some settings that allow half speed and backwards playing of your loop. I love this pedal and I have a hard time seeing myself let it go after all we've been through.
Complete to me!
This is a great delay pedal and have so many combinations to use! But this have some bug's, 1/8 and more, with some practice u can use this!

Mainstay
Hours of fun. From simple analogy delay to faithful reproductions of effects that are now veritable antiques & impossible to obtain -it can be a complex pedal but great to have this array of options in one stomp box thought it does take up a lot of real estate.
Have owned mine since 2000, no issues but I believe some people are not faring so well w/ older version of theirs.

Perfecto para hacer rarezas y efectos interesantes manualmente.

Not knocked out
I know this is the most ubiquitous modeling delay on the planet, but I really do not like the DL4. I am glad they invented this 4 button format to be copied by companies like TC Electronic, but I just could never get into the sound of this thing when I owned it. It lasted maybe 2 weeks and went out the door! I did really dig that filtery delay model for creating wild portishead HPF repeats with increasing resonance and cutoff. This pedal also seemed to compromise my core guitar tone even when disengaged. I felt it compressed everything and cut my bandwidth some. I hate that. the tap worked well though, and that's good as were the silent switches. Not for me though. I apparently still have one of these but it seems to be broken. Color me surprised.

Incredible Delay Pedal
This is one of my most used pedals by far and I could not be more happy with it. Though size wise it is rather large, if you really care about delay, you will make room for this powerhouse of a pedal. With countless banks and programable and quick-changable presets, this pedal can switch independently between 3 different presets at a time. The tap tempo helps a ton when you need to make last minute speed adjustments on the fly and has come in handy several times live. The DL-4 is used by some of the best in the business and for good reason. Whether you want quick snapback delays or huge (and I mean HUGE) stereo ping pong delays, this pedal can do it all. For cheaper than most EHX pedals, the only better pedal that I know of in terms of delay is the Strymon Timeline (more than 2x the price). To sum up, this pedal has never let me down, extremely well built, and can create about any delay sound you can think of. Do yourself a favor and go get this pedal as fast as you can.

what about the Flashback Xx4? not as awesome as the timline, but much better than the Line 6 in many respects

What can I say that everyone else hasn't?
This is a beautiful delay pedal that I use mainly for swells since I lack a volume pedal, but I also use it for extending copies of my tape and analog delay repeats since I like how the copies degrade with time. I used to own a DD-500, but it was stolen and I used to think that this was a piece of shit pedal just because of the way that it looked, but as you can see I was so wrong and it is now crucial to my overall sound.

Nice delays and looping.
I would have given it 5 stars but some earlier production runs were little vampires. They'd suck tone from your instrument from the moment you plug in. Other than that this is a great delay pedal with several mods available out there. The loop function is fun.

all the ones I've tried were tonesuckers and the delays have a plastic quality I cannot get next to

Ya know I felt the same about it not sounding quite right at first. I got a pretty good deal on it and I liked the looping and reverse features on it. The delays eventually grew on me. I think it sounds best in stereo. It can sound a bit muddy in mono for sure IMHO.

I am a bi-amp guy so I've never really used one in mono except for that tweaky resonant filter delay on a recording one time... its better in stereo, still weird sounding compared to TC stuff of the same era like the delays in the old G sharp rack

the delay of delays
These delays are classic, not much tops it. Enough different modes to keep everyone happy and trust me theres tons of room to experiment with. The looper on this board is a very nice bonus, plus everyone should play with a loop pedal at least once. If you have a little bit of money for a decent delay then look no farther, this pedal can and will delay it all

Great delay and looper
No wonder why lot of artists still use this 10+ year old model. Sounds very analog and the swell function makes it exceptional.


One of the best and most complete delays. A classic.
A very complete and open ended delay. 3 presets. Tap tempo. I love the loop feature. I own two of this. I use them sometimes for looping and the other one for delay. or at times, I use both for loops. I love its play once, reverse and half speed function. You won't find that in a delay, except for the Strymon Timeline, but just to have the features this pedal offers talking about loops, you'll spend like twice the price of a DL4. The downside is that at times, I used to have troubles correctly powering it. (it uses supposedly 2000ma). Also, I haven't experienced it, but I've heard that sometimes the switches fail. They can be changed, but I guess it's normal. According to its use. To me, it's better than the Flashback and the DD20. Haven't tried the Eventide or Timeline.

Haven't even begun to imagine the possibilities
Many delay types to cover all your delaying needs! 3 pre-sets and built in tap tempo. Easier to recreate the delays of some of my favourite songs because it's used to widely.
Second hand is the way to go, they are coming down in price, and so definitely worth the buy.
Cons: Delay and Looper cannot be used at the same time. Footswitches CAN (hasn't happened with me) break
My personal wish: I would like to get it modded with new footswitches and LED's, double the memory presets to 6 and separating the loop function. All these mods can be done to it and they can all work together, it's just finding a modder in the UK & Ireland.

Great!
First pedal I've ever bought and it's still my favorite!

Great creative tool
My first delay pedal, and still a mainstay on my pedal board. I cant get any other pedal to do the spesific sounds I rely on it for. It has its quirks, but that only gives it caracter and makes me tweak out sounds only I have a use for. I can't imagine ever letting it go.

One of the most versaitle delay pedals ever made
Brilliant delay pedal which allows for whatever delay sound takes your fancy. However, i believe this pedal would be completed with a dotted eighth or something similar function to accommodate for all delay tastes and to add even more flexibility.

Time got over it
It's a classic from a past where it came to set its concept as a standard for then on, but then time came with alternatives that can just put this unit into shame. Today there's no much to think about between this and TC's Flashback X4 in the same price range: the X4 gives longer loop time, better sounds, MIDI capabilities, more presets, more tempo flexibility (dotted eights!), TonePrints, updates, and all of that in an even much clearer interface and streamlined design.

Wonderful!!
What I really love about this pedal is how much you can experiment with it while using the expression pedal. The way the sound reacts simultaneosly with the pedal action turning the knobs is simply awesome! The crazy feedback madness that can happen when you turn its knob to maximum drives me wild and this pedal seems to me like a magical beast you can never fully understand. On top of that the variety of effects plus the looper are just way too much. This pedal spoils the owner. And I keep on thinking if I could I would have more units and some that I could keep in an underground bunker in case of apocalypse.

This is quite possibly my favorite pedal of all time
I might get the Empress delay plugin at some point because it's so ridiculously powerful and configurable, but I have used the Line6 a ton and all of its modes sound so good they sometimes make me want to cry. Also, its built-in looping and triggering capabilities are all I've ever really needed for my guitar.

green box magic
Fantastic and now classic (?) delay modeler. If you neen clean crisp delays, its got you covered, modulated tails, that too. Its not the best thing out there but it covers SO much territory that its remained a part of my setup. Great on aux sends for dub sessions due to its hands on nature.

Bought it for the wrong reasons but love it!
i thought this would be a crazy good loop station, that's not necessarily the case, or at least I can't get it to operate as such, it's basically my favourite delay because of its presets and price point.

Buy this pedal now
its great how you can save 3 different delay modes as well as have tap tempo. this pedal is amazing
Line 6 Dl4
My main delay (though I have three on my board). Great sounding delay, I use the Digital delay setting, the Sweep echo setting, and Analog Echo setting.
