Good settings on multi-effects pedal for ukulele?

I just got a zoom g2 effects pedal and I've been experimenting with it. Some effects sound great while others don't. Does anybody have some suggestions about effects that work well with the uke?

I made a video (my first) showing a few riffs with the effects that I thought sounded good.

Not sure about the g2, but I have a 505II. I've messed around a little bit with it. I've used it in my "I Want to Break Free" video for the solo on setting D2.
