Man, what a great app. Totally blew away all my expectations.
Love the ability to slow down tunes to learn them while still keeping the proper pitch. The little virtual amp sounds pretty amazing. The iRiffPort is a little pricy but you forget what you paid for it pretty fast once you start using it. You could actually use your device as a preamp for a gig with the line out on the iRiffPort and it would sound really good. Better probably than what your using unless maybe you have a GK set up already. The gate valve effect is excellent.
