Hi,
Re-reading through the thread I now see that I wasn't understanding what was going on.
iShred is a standalone virtual guitar app, it doesn't work with a real guitar.
We took the effects engine from iShred and build iShred LIVE just for people who wanted to play using their real guitar. iShred LIVE is the only guitar enabled app, the basic functionality free, with in-app purchases for additional effects.
I apologize for the confusion and that I didn't pick up on this earlier.
That being said, iShred is a great app to have around when you aren't near your guitar. Easy to setup songs, effects, and practice or compose on the go. The built-in AirPlay feature lets you tap into over 3,000 songs uploaded by fellow guitarists around the world. Our apps support AudioCopy/AudioPaste, which lets you take songs composed in one app over to the other apps for layering or as backing tracks.
Still, if iShred doesn't fit your needs you should contact Apple about getting a refund.
Best,
-Jerry
