  • well worth it, get one.....

    As reviewed by jamm4mee2.... on 11/15/2009

    Got this thing 2days ago,love it! Great for the begginer in every way or any level player looking to practice different styles. But theres much more. you get recording 101 and then some.the effects & pre-sets are solid and you can tweek themm all.The drum&jam tracks are good but,a few sound muddled...ONLY a few...I found that with jams best to use headphones or studio monitors.Amps dont sound all that great and adjusting everthing to compensate is a real drag... Even more so modeling amps... With that said I give it 8 out of 10. No on off switch, and some of the controlls and features arent as useful as I'd like.And there is no practicle live or stage use. but I love this thing. And its solid quality. I strongly recommend it..Hey and with headphones it goes anywhere.Go to the Line 6 site for more info. I did. then go get you one...

  • more like 4 3/4 stars

    As reviewed by scott on 4/29/2009

    i'm very much a novice player and almost never have the chance to play w/ others. the jm 4 has completely changed my guitar world. i've had it for two weeks and am still going through the presets: tones; beats; jam tracks. there is so much in this little box. the tones are already set to match the jams and the key is already given too. i think you can also change the given key but i haven't made it that far. i've found my playing stuck in the blues box as of late but now now it is all over the place. the jm 4 is so much more than just a looper. but nothing is perfect. it could use an on/off and some of the tones are similar but with all you get, who cares? it is so worth it. if you were at all thinking about getting a looper, especially if it is because you are playing alone, this is the one

  • A Very Nice Practice Tool

    As reviewed by E.Folkes on 10/2/2008

    The Line 6 JM4 Looper is a very good product. For those of you who do not have other people to play with It's jam tracks are very well done. If you are learning the 7 modes of the major scale, or your pentitonics it is perfect to play those over and get a feel for what it is like to play in a band. The thing I like about it most is that if you like a particular backing track you can go in and change the tempo and key of it and practice your scale modes in another key using the same backing track. You can also make and layer your own tracks. It's also not to complicated to figure out. Ok for the negatives an on/off switch would have been nice, but there is not one. Some of backing tracks might sound a little distant but it is not so much that I wouldn't recommend it. Anyway it is well worth it to hone you skills. If you are contemplating getting a looper do check this one out.
