Just ordered a basic looper pedal. Don't know much about them. I do a bit of solo work and what I would really like to do is play a bar (or 4 bars), record it and loop it so I can play a lead break over the 4 bar loop. I assume this is what they do? Only problem I have is that I play to a drum machine backing and was wondering when the loop repeats if it will be in synch with the electronic backing drums? ANyone doing a similar thing or am I off the mark here?
