The JM4 is a very powerful looper pedal, and there is A LOT this unit can do. Here is an overview of the main features, but there's nothing like checking it out for yourself.

One thing I should have mentioned in the video, is that for each song you load, the key of the song is indicated.

It has become a great tool for my guitar teaching job. It's so easy to load up a drum groove and hit the play/stop button with my foot.

For those of you who would like a "jam buddy", please give this unit a try. Your local music store might have one you can try out.

It's very convenient to have the JM4 around for practicing or for coming up with ideas for songs. You can practice scales, arpeggios, technique, leads, rhythm, etc to either any of the songs or just to good drum grooves. You can go from the JM4 into your amp, your computer, or just use headphones. That way you can jam all night without disturbing anyone.
