Query: Only scratched the surface...

I am only a beginner at guitar. When I first started learning I was just using the amp's overdrive and that sounded just OK. After getting the zoom pedal I found that I was practicing a lot more simply because it sounded so much better! There are 40 preset effect and after playing around with them I figured out they are modeled after a lot of my favorite tunes... thus I practiced even more! Also, part of my practice routine is to do some finger exercise drill with different scales and a metronome... kinds boring. But doing it with the Zoom's built in drum machine is so much better!I know i have only scratched the surface with what this thing can do for me but so far it is already worth the 89 bucks.
