Feature:
The only drawback I have found so far is that you cannot sync the looper with drum machines, but there are ways around that! C'mon....musicians are supposed to be creative!

Quality:
The only problem I have seen is that the output level pot was a bit erratic in the mid position. I overcame that by running it at full output and adjusting the input trim on my mixer. Other than that, it appears to be built like a tank! I have a rather elaborate set-up, and I often need to stomp on two pedals at once. I say "stomp" because to make sure I get both pedals with one foot, I position them very close together, and STOMP! I've been stomping the s**t out of this pedal for over a year now with no problems. My tech says in his experience that Digitech has had some internal reliability problems with some of thier other gear so I will probably get another unit as a backup just in case.

Value:
Without a doubt. There is another company producing a similar product, and from my experience, and from what I had heard from other people, the Digitech is the one to get. (Just to be fair, I do own a lot of gear made by the other company, and it is great stuff!)

Desirability:
This piece of equipment has made a tremendous improvement in my act. I would use it even if it was flaming pink and took up more room than my FOH speakers and ate 9 volt batteries like candy. But it doesn't. It just sits on my pedal board waiting to be stomped on so it can do it's job

Sound:
This unit is awesome! I don't pre-record any of my loops. Instead, I take an effects send from each channel of my mixer that I want to include in the loop, and record it live, then play it back and add whatever else I want. The playback sounds identical to the original once you get all the levels set.

Ease of Use:
VERY easy to use. I had to give it a "9" because of the sync issue noted above, but once I got that problem worked out everything else was a piece of cake. The only other minor problem I would like to see changed is that you need to hold down the pedal for a few seconds to erase a loop, and watch for an LED to flash indicating the loop is erased. For live performance, an instant erase feature would be nice

Support:
I was unable to locate the auxilary footswitch that goes with this looper, so I called Digitech and they emailed me a schematic so I could build my own! BTW....it is not just a basic switch. There are some diodes that allow 2 switches to perform several functions.

Overall:
If my looper was ever "lost" (AKA stolen!) I would immediatly go out and buy another one, and then hunt down the bastard that stole my first one and beat the living shi.......Opps, sorry! Really, I am always looking for improvements in equipment since I do this for a living, but for now, I don't see anything that would work any better than the Jam Man. So far I am 100% satisfied.

Feature:
the feature of the jam man are decent. i don't know what other features i can expect out of a phrase recorder. the different drum kit feature is cool. but of course what is more amazing is the 24 minutes of time you have on this sob. and if i get a 2gb compact flash card for it, my time will be 6 and a half hours. that's crazy. it's just too bad those cards cost a butt load of money.

Quality:
i think it's made well. but not good enough to asure me of it's waranty.

Value:
yeah, it's definitly worse it. but the flash cards are too much

Desirability:
doesn't look that apatizing.

Sound:
the sound quality is very good. you basicly get the exact sound out from what you played. no worse, no better. just the same.

Support:
i haven't had to deal with digitech yet. digitech is not my brand. i just wish Boss could have made something better. how dare digitech out beats Boss. but why should i complain. 6.5 HOURS

Overall:
it's good. i don't think i can find a better looper than this. i mean, 6.5 Hours. what the hell? with me, i could allways use more time.

Feature:
The unit has some nice features compared to the boss 20xl. On the jamman you have a usb port and a compact flash card. You can use the USB port to transfer loops to your PC, but I don't use it because I find it easier to just take out the card and plug it into the card slot on the front of my PC. One thing I wish it could do is...... I wish you could mute the live sound and make it only play the recorded stuff. That way you could plug the jamman into one amp and your guitar into another amp, then the one amp would only play the recorded stuff and the other would play your stuff. That would make your performance sound clearer and less clutered, becuase if you ever used a splitter and pluged two guitars into one amp, you know it can sound pretty bad. I also wish you could turn in the tempo because if you know a certain song is 150 tempo then it would be better to just rotate to it then try and guess what 150 sounds like.

Quality:
The pedal itself is really strong and is made out of some kind of metal. But one problem with the metal on metal is when you phush the foot pedal down hard it makes a big clank noise...... I plan to get some padding and glue it under the pedals. There is one major problem with this pedal though. The flash card!! After the first couple of days I got the pedal I noticed my loops where getting screwed up and some of them were mixing into each other. Now this is a big problem! luckly the patches I had were just me messin around and nothig serious. What I was doing that made it screw up before was... Record loop on patch1, then one on patch2, now copy patch1 to patch3..... after doing that patch1 leaked into patch2 and screwed up the loops. It was doing it tonight and I reformatted the card and tried to get it to screw up the loops again by doing the same thing, but it seemed to be okay (only tried it once though cause my family is sleeping now). I have read other reviews that said the loops were getting screwed up too, so its not just my jamman.

Value:
I haven't tried any other loopers, so I can't really say. Aslong as you don't add lots of overdubs, change the tempo, or copy loops back and forth, you should have any major problems with the loops getting screwed up.

Desirability:
I already have it, but I will just think back to when I wanted it. I really wanted this pedal, so I could jam to some sogs I made, and have some fun. THe design is realy cool and all the extras like USB, flash Card (although not the good), and tempo change made me want it even more.

Sound:
The sound is really good. You just have to set the volume knobs on the thing correctly.

Ease of Use:
Its pretty easy but to change to other loops you have to buy the foot switch for it. But erasing and overdubing loops is easy to do and you can do it hands free. You can set the tempo (hands free) with the right footbutton, but it would be nice if you could also rotate the knob so you know you have the exact tempo you want. It takes a while to get used to the pedal and to be able to make loops play smooth, but I find it easier if you put in a tempo first then start on the click.

Support:
N/A

Overall:
Its a pretty nice pedal but when the loops get all screwed up it makes you want to scream! The new boos looper is coming out soon (or already out) so if I ever have a bunch of money and want a new toy I may get the new boss looper.

Feature:
Having the pedal to change loops is key. You gotta have it. Looper Tools software is an excellent add on, and worth the price.

Quality:
Built like a tank, but it does not work cosistently.

Value:
It would be a great deal if it worked consistently.

Sound:
The sound is fine. What goes in comes out.

Ease of Use:
I used it on a gig the day after I got it. No problem.

Support:
I have sent this back to Digitech twice, because the unit has forgotten how to recognize input signals. The support people were great, but they have not fixed the thing so that it stays fixed.

Overall:
I have had issues with the unit recognizing input signal (both instrument and XLR). I never know from day to day whether it will work or not. When it works, it is so easy and sweet to use, but I cannot use it on a gig, because I just don;t kow whether it will work.

Feature:
amazing features.. i wish this thing was reliable for live use!! i want to keep it but i can't!

Quality:
the hardware seems good.. nice and sturdy.. the software however is a nightmare.. this thing "skips" like a cd sometimes when you try to overdub multiple parts.. (the whole point of looping).. crazy!! i'll have to take it back.. i'm crying about it right now because this thing would have been AMAZING!!! 99 loops?? usb?? AWESOME.. too bad i could never use it live like i had intended... hopefully they will get their act together and release a fixed one!! (from what i hear this glitch happens to other people too..) trust me i'm a pro.. this is not user error.. even if i've previously looped drums and i'm trying to overdub overthem the original loop will loose it's tempo and SKIP!?!?! random!

Value:
oh man.. i REALLY wanted this to be the dream machine that it would be if it we'rnt so glitchy! i'd love to keep it as a practice tool but it's too expensive for me to do that.. guess i'm getting a red box.. aw man! only 12 loops? i'm bummed

Desirability:
i say it's the worst because it's so decieving.. i WANT THIS (if it worked)

Sound:
sounds great.. makes me even more sad that it malfunctions all the time

Ease of Use:
this thing is very easy to use.. too bad it "skips"

Support:
i'm just returning it to ZZOUNDS who's support is great.. i don't know about digitech

Overall:
long story short, i was hyped SUPER exited and now i'm pissed.

Feature:
Great features if they would all work consistently.

Value:
If it was not for the strange behavior, it would be GREAT for the money.

Desirability:
It sounded so good on paper, but.....

Sound:
No problem what soever with the sound quality.

Ease of Use:
It took me around an hour to figure it out because it did not always function as expected.

Support:
The hardware is well made but the software is quit buggy.

Overall:
I will take it back ...

Feature:
It would be nice if you could mute the live imput at times but overall I am ha[[y with the features.

Quality:
So far so Good.

Value:
Worth the money.

Sound:
I play a Taylor Expression System and find the sound to be quite good using the low impedence plug through thr microphone imput.

Ease of Use:
Used it at a gig right out of the box. Some practice helps but very short learning curve.

Support:
N/A Haven't needed any!

Overall:
I expect years of use. Both practice and gigging!
