IK Multimedia iRig Stomp 

IPHONE STOMPBOX INTERFACE

There are tons of gadgets that let you plug your guitar into your iOS device, but that’s typically where the signal stops. The IK Multimedia iRig Stomp is a simple stompbox-style device that passes the incoming signal to an iPhone or iPad and returns the result back to your guitar rig. It’s a great way to add iOS app-based effects to any live setup, practice with one of the looper apps on the market, or even re-amp guitar tracks in the studio.
