Our guitar cable is the right cable with the right set of connectors to turn your iPhone, iPod, or iPad into the most portable guitar rig practice room/studio you've ever used. Connect the 1/4 plug to your guitar, bass, or keyboard; connect the 1/8 plug into the headphone jack of your iPhone, iPod, or iPad. Then launch iShred Live or other instrument effects app. Your iPhone, iPod, or iPad is now an awesome handheld stompbox. And there's a jack for your headphones or line-out. iShred Live is an app that gives you an eight-effect pedal board with digital tuner, metronome and playalong/practice player so you can play along with a song, or practice tricky sections. With iShred Live and our cable, there's no need to lug out the amp (and no more neighbors yelling for you to turn it DOWN). And you don't have to sacrifice your effects loop for privacy or portability. It's all right there in your hand: a super-compact practice rig you can use with your headphones to rock wherever you are, whenever you want. Tuck your iPhone into a pocket or hang it on your belt, and you're playing without being tied down (excellent for flinging windmills on your coffee table). Use it with your headphones, or plug in a standard 1/8 (3.5 mm) stereo-mini jack audio cable (like our own Auxiliary Audio Cable) and play through your home stereo, amp, control board, mixer, whatever.
