The iStomp works like every other stompbox. Step on the footswitch to turn it on and off. Adjust the knobs to dial-in the sound you want. The biggest difference between the iStomp and other stompboxes is you can completely change the iStomp to any pedal in the entire pedal line. Simply connect your iPod touch®, iPhone®, or iPad® and choose a pedal to load to your iStomp. In about the same time it takes to download a song you can turn the iStomp from a distortion to a reverb, a phaser to an overdrive, or a delay to a chorus.
iStomp includes two free pedal downloads ¬- DigiTech's Total Recall™ digital delay and Redline™ overdrive to get you started.
