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.

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

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.

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.

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.

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.

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

That's the sound of your mind being blown.

This pedal was my intro into delay. I rocked it for ten years until it gave up and once a Line6 pedal is done, it is done. The sounds just blew my mind. I used the Tape Echo, Tube Echo, Lo Res and Analog at all times. Four stars because of their short life.

Great buy!

The Line 6 DL4 has many good options for any artist. It has the precision options I like and a great 14 second looper. The good thing about the looper is that it has many effects, with a half time (which can be used to double your loops speed when used craftily) and a reverse looper effect it can be handy, I use it in tandem with my Ditto Looper.

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.
