iShred looks like an iPhone guitar app that actually looks usable, assigning chords to buttons at the top of the screen which are then played with a strum of the strings. Best of all, the system has a set of stompboxes for your amping pleasure including tremelo and looping. Overdrive, anyone?
I’ve used a few great guitar apps and the screen is just too small for real finger placement (Isn’t it funny that that I can actually write that iPhone guitar apps don’t let you play guitar well enough? Imagine saying that just two years ago.) Assigning chords is a considerable improvement, it seems, and should allow anyone able to play “Enter Sandman” on a phone in public without sounding like a fool.
