Feature:
It has a lot of features. Lots of 'em. They're <b>very</b> confusing to use, provided i never got a manual with it. That's a letdown. However, the loop sampler is a great amount of fun to experiment with, as well as the sweep echo. This pedal keeps me amused for hours on end. And it's gig-worthy.

Quality:
Built like a truck, looks like a...well...stomp box, really. I just love the <font color="lime" face="comic sans ms">green</font> chassis. It suits it quite nicely. And that happens to be a <u>very</u> nice hue. It hasn't broken on me yet, and i've forgotten to turn it off overnight. Because i'm just that stupid.

Value:
Considering i got it free, i guess you could say i'm getting my money's worth. Hah. But it is quite expensive for those who purchase it.

Desirability:
Generally. Just wonderful. It's quite the sound, quite the style, and a wonderful addition to my rig.

Sound:
The sound quality is crystal clear, though tracks with distortion too heavy tend to cut out. Oh well. It's probably just my crap amp. The loop sampler is sweet and all, but i think it'd be handier if you could record for longer, then solo for longer. Guess what! It doesn't just stop at guitars. Nope, i plugged my band's mic into it, and did some amazing echo work with vocals. It's a very useful gismo to have handy, even if it is substantially more expensive than my amp.

Support:
I have not dealt with Line6

Overall:
The novelty seems to have started wearing off. I'll keep it around though. Voice effects are fun to mess with. I think this thing is just marvellous for what it does. If it were stolen or lost i'd certainly buy a new one, to avoid a red-ass beat down from my cousin.

Feature:
Power Adapter not included, but I feel it should be. 4 C batteries? No thanks.

Quality:
great. totally reliable.

Value:
Totally worth the money

Desirability:
Great

Sound:
If you can imagine it, you can do it. This pedal is amazing.

Ease of Use:
Read (or at least look at) the manual.

Quality:
It's great... that's all I can really say to describe it. It's well built, very sturdy. The main problem that I have is that the volume knob keeps sticking, but I did get it from B stock, so it's used. GREAT!

Value:
Great value.

Desirability:
People like it, but "sex appeal"? Not sure, I'll have to go find out!

Sound:
The sound is superb. I mainly use it for the Loop Sampler. I use it with my electric violin. As a violinist, I am very picky about sound. This unit does great soundwise, but does dull the sound of my violin a bit, but that can be made up for. Add some reverb, and it sounds great again. The delays are great, I especially like the rhythmic delay, and the reverse setting is a hoot! I give sound a 9 because it is great, but dulls the sound of my instrument a tiny bit.

Ease of Use:
Everything is quite clear, and it's very easy to learn how to use. I was using almost perfectly in the first day, so there's not a problem here.

Support:
Haven't had to deal with them.

Overall:
It's all good!

Feature:
I love the idea of an expression pedal for delay. What an awesome concept, now I can make my guitar freak out AND play at the same time!

Quality:
I got it used and it's in great shape. I don't think it's going to get messed up too easily, I've seen lots of touring bands use them.

Value:
I bought it used because they're damned expensive.

Desirability:
I absolutely had to have one. I NEEDED it.

Sound:
it can do ANYTHING and sounds great even when it's off.

Support:
I haven't had any dealings with Line6 at all.

Overall:
I don't think I need any more delay effects, and I just have the one. I'll get the expression pedal, though.

Feature:
only 3 user programs is a big pain in the ass, this could have been solved by the inclusion of a 'manual' switch so kicking it on would let you use the current knob positions so can be a bit of a pain for playing live. Adding the expression pedal is a great feature but the lack of midi connectibility is annoying too.

Quality:
Built like a tank and a decent power supply for a change. HAve used this unit live, for rehearsals and in the studio for the last 2 years and never had it fail on me.

Value:
Great sounding unit, has a few drawbacks as detailed above but don't really know of any comparable unit - expensive but imo worth it for the amount i use it (ie all the time).

Desirability:
Looks cool (like mission control or something) mines getting a bit scratched but good shape (plety of space between the switches) tweak and tweez as controls cute. Has become an essential part of my guitar set up, although it weighs a ton.

Sound:
This thing sounds great and adds all kinds of effects if used creatively. Loop sampler is good but it would be nice to be able to select whether previous loops fade or not, you can't build forever. In addition to this you get saturation pretty soon with repeats all the way up. All the models are really useable tho. Only real drawback is that it can occasionally repeat the click of the switch when you go from one delay to another. Have also experienced clicks when using short delay times on the reverse setting as well so not 10 out of 10

Support:
never needed it

Overall:
Great at what it does, can't imagine a delay that would give you more features etc for the type of unit it is (stompbox). If it was lost/stolen (not much chance of it breaking!) I would go for another line 6 - might stick with an echo park tho as wysiwyg controls and more compact or an echo pro if i had the cash. Having said that i have used it for everything (synths and vocals as well as guitar) and the sounds are fantastic its all about the interface - the lack of more presets is the biggest drawback as far as i'm concerned so would recommend it - esp if not using many diff settings in a live context.

Feature:
Brilliant features really easy to follow

Quality:
Homemade american delay MMMHHH !!

Value:
Quite expensive but it is damn sturdy !!

Desirability:
OOOOHHHH yeh it has a nice body.

Sound:
The best delay in the modern world

Support:
I have never had to contact line 6 for any reason.

Overall:
As it says the best

Feature:
Line 6 would do well to re-design their DL4 and instead of knobs they should use a scroling backlit LCD display like on some of their pricier multi effects units. This product has been out quite a long while, they should do an updated version...smaller, slightly more durable with actual pedals instead of small, easy to miss switches. The AC adaptor (sold seperate?) is needed, unless you love paying for large, costly batteries... The Line 6 power supply isn't too expensive and works with all the stompboxes, a NEEDED accessory, otherwise you are ready to go. All of the delays are useful, if you're creative and willing to turn knobs! I can't remember ever gigging with this in a regular "band", but I've used it extensively to crate soundscapes and layers behind vocals, samplers and keyboards. Aside from the great settings and the loop sampler, it's purely fun to make noise and see what kind of repetitive walls of sound you can create. Be kind to your pets if you own any and turn your volume down or play somewhere soundproofed, as animals really hate this thing's more severe sounds.

Quality:
My personal DL4 has the appearance of a large aluminum doorstop and I have never had ANY probems with it, 4 years in. If I were to gig actively with it, I would buy a second unti, keep it in the box, in my trunk in case I needed it if it were crucial to my music style. The green paintjob is sweet and has yet to chip or flake though I have seen others DL4s painted over or paintjobs cracked. Take care of your DL4 and it will serve you well, avoid spilled beer and excessive heat or cold or moisture and don't drop it, that simple!

Value:
Hard to tell, there is no other box out there, still! that can do what this box does, so yes, in a way it's worth it. It's worth it to me becasue it is so much fun and i am always discovering new stuff to use it with.

Desirability:
It should be a no brainer for any noise artist or experimental musician who does not comply with "the rules" of music. I am drawn to the mildly metal flake hulk green paintjob and who can keep their hands off of several knobs and switches. technically, though it's been out for a relatively long time, it still blows me away and is as an essential part of my day as my iPod and my pocket knife.

Sound:
This is the ultimate delay toybox in one unit. A must for experimental/open minded musicians. The Loop Sampler feature is worth a third of the price alone! It can be used to create walls of repetition or you can loop a rythym then play a second part over the top to practice or hash out ideas. I've had my DL4 for about 4 years now and it's never taken a dump on me when I needed it to perform! Many people complain about Line6's durability but I have no concerns. Just keep your Line6 gear dry and in a safe case. I keep mine, with it's power supply, in a cheap, foam filled plastic gun case. it's water resistant and crush proof. These Line 6 boxes are not built like the venerable Boss bricks of yesteryear. It's newer, digital gear which requires a little more care. All of the delays sound true and clean and I have had no problems with excess noise or hum. You could easily invest several thousand bucks, trying to add new fx to your loop, or you could drop the cash for the DL4! The sounds are, duh, digital emulations of famous delays, so don't expect a true, warm organic analog sound on all of the presets, though most sound pretty darn cool.

Ease of Use:
Plug into and out of it, attach power supply to wall or power strip and BAM! you are playing with some killer delays. I put a cheap phaser and a flange behind it and got some very "talky" vocal tones from it.The manual offers some clear advice but it's more fun to learn what things do on your own. Sounds great with bass too...

Support:
I called Line6 on behalf of a friend who is an all tube "digital hater" kind of guy. They filled me in on the manufacturing process and gave me a basic rundown of what its guts are all about. They were pleasant and knowledgeable, but they didn't offer me anything cool like stickers, hats or catalogs. I wish they would have sent me some schwag.

Overall:
This thing has made me into a delay nut. I wasn't sure but bought it from a friend who was moving to Europe. I love it and would shell out retail to get another one if this one gave up or gets wrecked. My favorite aspect is the Loop sampler, I may still get a Boss loop station, but for the price, and the features, the looper on the DL4 can't be beat, and it's only a small part of the whole versatile package.

Feature:
Love having 3 presets and a tap tempo. I can set-up three models use them all night tapping in the tempo I need for various songs. I don't use the looper.

Quality:
I read lots of people having problems with their DL4. I bought one anyway. I love it and grew dependent on it for some great sounds. Then mine broke. I got it fixed under warranty, see Support. I used my Boss DD5 as a backup, but really missed having other models and three presets.

Value:
I'd like to see better reliablity for $250. I think the DL4 is really worth $150. But I bought one and I recommend it.

Desirability:
Too big on my pedal board. But I have a small board that fits in a computer bag.

Sound:
Sounds great. Most models are very usable and the true bypass sounds great in my effects loop.

Ease of Use:
You'll need to memorize what knobs do what for each of the models you use. Or you'll spend time figuring it out in between sets. However for the versatility, it is worth having to know a little about your gear.

Support:
Line6 was outstanding. I took my DL4 to Wells Electronics in Orlando FL. He kept it for 2.5 months then told me to come get it, it was still broke. Line6 extended my warranty and gave me several options. I took it to Hendrix Sound in Central Florida who fixed it in 3 days. So, Peter Wells from Wells Electroncis - Bad ... Brian Hendrix from Hendrix Sound - Good. Whatever you do, don't go to Wells Electronics.

Overall:
If you need more than one type of delay, get one. I play in a three piece and on various church teams. I need versatility and got it in the DL4. I also run my modulation effects though my effects loop in a high gain amp. Any noise is a big problem. The DL4 sounds great.
