If your iPad or iPhone is set to play a starring role at your next, sold-out concert, you may want to check out two new, iOS-friendly interfaces from New Signal Process. Pictured above is NSP's BreakOut Stomp -- a die cast aluminum-encased pedal that promises to transmit guitar signals to and from your iDevice, without any unwanted distortions or detection interference. All you have to do is slide the stompbox into your pedal board, hook it up to your iPhone's headphone jack and fire up your favorite recording or mixing apps. Whereas the stomp was designed with guitarists in mind, the recently unveiled BreakOut Stereo is geared more toward the DJ demographic. The device offers essentially the same iOS-interfacing capabilities of its pedal-based counterpart, serving as a portable conduit between an iPad and an amp or tabletop unit. Boasting two mono output jacks, this little guy can also be used with guitars, mics or mixing boards and is durable enough to survive the rough and tumble of your next world tour. As far as prices go, the BreakOut Stomp is selling for $155, whereas the Stereo will set you back $135. Groove past the break to see an image of the latter, or hit the source link to find out how to order one.
