So weird to come back, haven't posted here in years, but nevermind.

I have a project, a jazz duet: Guitar and vocals playing jazz standards.

The things is, i would like to improvise a solo in some of the songs but i want to keep the chords playing in the back (and until i grow another pair of arms, i'm going to need some help to do it). I've read that you can loop the guitar on ableton live but i'm ignorant when it comes to that software.

So, any knowledge on how to do that?
Have you thought of just buying a looper pedal? You can loop yourself with ableton, but it would be cheaper and easier to just use a looper pedal.

If you would like to use a looper then I would recommend a digitech, boss or a boomerang.
