Thanks! Those tunes were such a blast to learn and teach. Yes it can be challenging to get all of those guitar battle leads together, but it's well worth the effort!

I don't have any first hand experience with harmonizer pedals, but I did a quick search and the Boss pedal you mentioned seems like a great value. You may want to check out some guitar effect forums as well as youtube videos to get a more complete idea of what's out there.

To my knowledge, there are no plans to teach Amanda in the near future. You can head on over to the Song Request Forum and request it there if you'd like!

Keep rockin'!
Mike
