cool sound and cool design

I noticed that average 9 out of 10 Japanese guitarists have this pedal, so I bought one. I love it specially the design

However, I'm experiencing some volume drop when using it with overdrive (Cinder) and distortion (HM2).

Preferred Settings + Usage:

I mostly uses it with tape delay and auto volume (i can swell with it)

amazing

Resells for very affordable price nowadays. The amount of different and insane sounds it can make while just being a single digital delay pedal is incredible and super fun. I don't use it professionally but it was definitely worth it just for the fun and sometimes beautiful sounds. Favorite and craziest mode is sweep echo.

One of a few pedals I've ever sold

I have few dozens of pedals and this one is a rare case, when I sold a pedal. I couldn't find a use of it. The delays are generic, the looper is too short. The size is huge, the power forces you to bring with you a dedicated power cable. There are more interesting delays than this, and they don't occupy half of your pedal board. On my board it was replaced by Avalanche run and Walrus audio Lore. *and still some space left :) No regrets.

chapersdale

Just Wow, what a pedal!

Bought this cheap off facebook sales on a whim. Best. Purchase. Ever. Versatile is off the charts, delay and loop quality is incredible. I've lost so many hours in an spacy ethereal delay induced creative bubble and I don't think I ever want to leave. The sheer number of amateur and pros alike that use this pedal should speak for itself. If you see one, buy it.

Preferred Settings + Usage:

Impossible to pick one favourite setting for this pedal. It does everything you want and more and it does it brilliantly!

Like most Line 6 products from this era: it sounds awesome, but the built is to be questioned...

Let's get this right out of the way: this pedal has all the delays one could want, and they all sound awesome.

Now, before going any further, in case you don't know Line 6 products from this series (DL4, FM4, MM4, M5, M9, M13...) that share those switches all eventually fail. At least, the tap tempo switch on mine gave up pretty quickly, under 6 months of playing in my apartment, wearing socks only. I also had a M13 that had some switches that would behave randomly when hit. Either I would have to hit it harder, or tap it twice to activate. It's a real shame since its enclosure is built like a tank and would withstand one's life of playing. There are schematics available online to help you swap the switches with soft, higher end ones that feels better and last way longer. Some companies will even do it for you (look for JHV3).

This problem is the main reason why people who buy it end giving up because, well let's be honest there are far better options on the market now and fixing broken things is pricey. My advice would be: if you can get your hands on a beaten one with broken switches for more or less $100, and get a tech to fix it with higher end switches. Because fix that, and you have a hell of a Delay pedal, one of the best actually!

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.

gchiaren

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!

the_last_factory

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.

ryanrbrown

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.

gigsucker

Just great

I use it only as a looper. Wish to have a few more!

Power supply is a pain in the ass, but it worth it. Haven't tried MKII, but judge some things already: small time limitation is a must, as well as losing recorded sample once the power is off. Otherwise we ended up with just tapping space on a laptop. Live sampling must be tricky and limited!

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.

12 alternative and related items for Line 6 DL4 Delay Modeler, curated by the Equipboard community.

Line 6 DL4 MkII

$211.00 - $249.99

newer

Line 6 has re-issued an newer version that is cheaper than a second hand original.

TC Electronic Flashback X4 Delay

$165.77

Vintage or Discontinued high-end alternative

It serves a similar purpose and took inspiration from the DL4.

Boss DD-7 Digital Delay

$123.99 - $172.12

Vintage or Discontinued similar sound cheaper alternative

Similar pedal, but more compact and has no looper. The looper in DL4 is not the best, so not a big a deal.

Boss DD-20 Giga Delay

$128.00

Vintage or Discontinued similar sound

The DD-20 has 4 presets, plus a 5th for whatever the delay mode knob is currently turned to. It's got a screen which is helpful when tweaking parameters, and legendary Boss build quality. The DD-20 is also a bit smaller so you'll have room for another pedal :)

Vox DelayLab

$90.00

Vintage or Discontinued similar sound

A great DL-4 alternative, and in many ways superior. No volume drop issues, "Seamless Bypass," and it sounds at least as good as the DL-4. The looper is great as well.

Roland Space Echo RE-101

$1,200.00

Vintage or Discontinued similar sound

Modeled in the pedal.
