This would be an excellent lesson series for guitar tricks. Every instructor always touts the use of a metronome, and I would guess that almost every student hates that incessant clicking with very little character or flair.

It would be welcome to see a series on some of the basics of using a looper pedal, and some generic rhythms in different keys that you could play along with.

I would venture to guess that many guitar players have looked for lessons on the loopers at GuitarTricks.
