iRig stomp looks like a stompbox, but it’s really a “stompbox interface” for IOS devices.
IRIG STOMP ($59) HAS THE VIBE of a rugged, pedalboard-friendly stomp-box. There are guitar In and stereo/mono 1/4" output jacks, an enable/bypass footswitch with status LED, and a Level control. iRig Stomp runs from a 9-volt battery (included), or a negative-tip 9-volt adapter. But there’s no effect inside—it’s an interface for effects loaded into your iPad, iPhone, or iPod Touch. You don’t have to use IK software, but you might as well grab AmpliTube Free and a free version of AmpliTube Fender.
iRig Stomp sends the guitar signal to the iOS device, where it’s processed via one or more effects, and then returned to the iRig Stomp. The connection is audio, so there’s no issue of 30-pin vs. Lightning. This arrangement does constrain fidelity to that of the iOS device’s audio, but iRig Stomp’s active circuitry increases headroom and reduces crosstalk/feedback with high-gain amp models. The outputs can go to an amp, powered speakers, or 1/8" headphones.
If all you need is to feed your guitar into an iOS device and send the output to some kind of monitoring system, the standard iRig (about $40) does the job. But the extra $20 for iRig Stomp also buys you a way to incorporate iOS-based effects into your rig. Furthermore, IK didn’t cheap out—this is a gig-worthy, all-metal pedal that’s built like a tank. So if you’ve been looking for a way to interface your rig to iOS devices— look no further.
