JM4 Looper

If your looking for a band members to practice with without having to get everyone together (And you know how tough that can be). The Line 6 JM4 Looper is it! Real user friendly, with great prerecorded tracks, drums and with the ability to record your own works of art. It's a blast! Highly recommend it.

This thing rocks!

I wasn't sure what to expect when I bought the Line 6 JM4 Looper. I read reviews good and bad, some criticizing the quality of the sound. It didn't take me long to realize that the JM4 is a great sounding unit that allows you to jam and lay down your own multiple tracks. There are tons of effects, songs, and presets and you can even run your mp3 player through it n play along with your favorite songs. Easy to use. I highly recommend this unit.

This is the single best tool I have ever used to improve my playing. We all get into ruts with our practice, so to dial in a groove (drums or drums+bass) you've never heard and devise rhythm and lead layers is the ultimate stretch, like sitting in with studio musicians...your "vocabulary" will go through the roof. The only minus is I wish I had more tone/effect control at the footswitches. Overall this is some of the best money you can spend to improve your playing.

Line 6 JM4 Looper

I just recently bought a Kustom 65 Watt amp. It is a very loud amp but a little tricky to get the right sound and tone dialed in. I bought the JM4 a couple of weeks ago. After buying the JM4 I was able to get the sound and tone dialed in right away. I bought it mainly for the looping effect and for working on inprovising. I have not used the looper as much as I thought. I have just been playing and inprovising over the Drums and Guitar to improve my timing. This was well worth the money. I love that it has a headphone jack, my Kustom amp does not. This allows me to play into the night and not distub everone. So far the only negative is no On/Off Switch which seems to be the norm for pedals and the JM4 should have the updated Firmware before it leaves the store. Great product, I am having a blast with the JM4 and my Drummer never takes a break or gets tired.

It's great!

This is most excellent. It is so good that I've considered writing to the Queen and Prime Minister about it.
