Hi guys, My friend has an iPad and a crazy Line 6 Sonic Port VX mic that doubles as the interface for plugging in his guitar. He's able to use his iPad for all his "pedals" and still output his sound to his amp. I'd like to recommend this type of setup to my bro-in-law because he also has an iPad (but no effects yet besides what's built into his cheap amp), but I think the Sonic Port VX might be overkill. We're starting to record now that I'm better setup for it, but rather than apply guitar amps & effects to his clean signal using GarageBand after we've recorded, it would be nice if he could control his own tone & effects from his iPad. What interface do you know of (besides the Line 6 mic thing mentioned above - again, probably overkill for this guy) that would allow him to plug his guitar into his iPad, but also allow the processed signal with effects to be sent to the amp? (I already have a preamp with 2 outs so I can send his sound to my mac at the same time as to his amp). Two noteworthy interfaces I found were the Apogee JAM and iRig2 - I'm sure they'll let you use the iPad but anyone know if we could get the processed signal to an amp from either of them?
