There are great guitar effects apps for iOS, apps which take the signal from your electric guitar and process it with weird and/or great-sounding effects. And there are also several Bluetooth gadgets that let you control those apps with your feet.
But what about the other way around? Is there a way to take a guitarist’s collection of old-school analog effects pedals, and control them from your iPhone? Well yes, now there is. It’s DC Pedals’ Bluetooth Looper and VirtualLooper app.
