All user reviews of 4/5 for the Line 6 JM4 Looper

Looper pedal with digital effects and SD Card. You can create the loop, or work pieces by loading backing-tracks, and even impress their friends by playing these songs with the accompaniment plays itself.

Effects:
- A damn good looper and almost unlimited because you can use an SD Card.
- The amp simulation: Clean, Crunch, etc..
- Delays with tap tempo, Phaser, etc..
- An efficient compressor.
- A separate reverb.

+ A box with integrated rate
+ Pieces on which to improvise (but useless in my opinion.

Connection:
- Guitar,
- Microphone with XLR input,
- Auxiliary.

UTILIZATION

The setup is fairly simple, but it's still a looper with effects, therefore, must spend some time on the manual is very well done.

SOUND QUALITY

Effects are sufficient at this level (this is not a multi-purpose either!)
The separate reverb is appreciable.
The compressor works well.
The amp sims are good but I'm not a fan. I prefer my Roland Cube simulation.

I use it with a Fender American Standard Telecaster and everything connected to my live stereo or headphones.

Sounds nickel!

OVERALL OPINION

I use it for 3 months and I am delighted. This is a very good camera in my opinion but a bit expensive new.

I have a problem: the headphone jack is a little jaded so robustness issue, it is a bit mean.

In addition, general way, it is for use at home, but for the stage, a specialized looper seems more appropriate (as you put too many effects, the sound is a little distorted therefore found not top: ().

Otherwise, for the rest not worry. And gained occas, I do it again this choice without hesitation!

I will pass on what has been said before.

UTILIZATION

Contrary to what is said below, you can obviously get rid of the count (they are still not mad at Line6), just 3 minutes to hack the device to understand (or read the manual!).

It works like any looper, it is accurate, easy and offers the advantage of either the sampler or the guitar mic which is great for use vocals / guitar (a pr button to switch between the other)

In addition we can separately equalizer singing and guitar ... which is great too!

SOUND QUALITY

For quality sound, it makes the case pr of small live (pub) but it will never be worth heads tube amp!
I personally played the acoustic Gratt and I never used the distortion.
And contrary to what is said, too, can have the pure sound of Gratt bypassing the amp simulations.

OVERALL OPINION

It is a small bracket that makes his job for a fair price.
Very beefy must throw a building to break it.
And with samples of its banks and it's fun, for work at home.
The looper function is perfect, and the micro switch vocals / guitar is unique and welcome!

(See other previous opinions and the site Line6 super explicit and complete)

UTILIZATION

It's simple but you have to read the manual a bit because everything is not super accessible intuitively through menus and submenus ..
The manual (very basic) is clear and can grip fast enough (but you must read!)

SOUND QUALITY

Well, next to my podx3 live, or even my Behringer V-Ampire (vamp 2.2), it sounds much worse (for amp simulations and effects, it is much more basic!)
In contrast, the loops recorded, the drums are real to jam on top (it is far ahead of BAR = these are synthetic backtracks level studio).

So two different notes: the first developed a 5 / 10
the second a 9 / 10

OVERALL OPINION

I use it for 2 months ...
JM4 excels especially in the quality of his recorded tracks (its loops drums / bass / accomp studio quality), the possibility of imports and exports songs wave (via SD card). In two months, however, I finally just used as an amp simulator / effects (because I had the pod x3 live at the same time !).... remains the looper large capacity, easy to cry, the tracks of presets for horse training or guitar ...
A super flat but for a very ....= c. there is no switch on / off, which means investing in a dedicated outlet with switch wire = more in the electrical installation .. . we wonder sometimes what some manufacturers think! ...
Well, I sold mine (cause underemployment) on another site, but pffiou here on AF, there is an ad dive group, which implies that the JM4 is a disappointing bike. However, it is a great looper (which is pretty normal for a looper!) Which, in addition, an amp modeling, a simulation of effects and presets backtracks excellent for jam (which is pretty good for a jam-machine!). I think I'll keep mine for loops electro acoustics (reverb very well made and correct delays sufficient to enhance my Ovation).
Looper as high-capacity, whose songs are biblios import / export via SD card, this is a recording guitar with undo / redo without breath work arrangements (for my part, I will not use, I think, almost never The amp models, and enter through the pieces of the electric in which I connect the pod x3 live).

But that said, I keep my "squirrel", na!
