I use this with bias and jamup xt pro, I would not suggest one that connects to the 1/8 inch connection, first off you will ware that sucker out and the sound quality is lower. Here is some stuff from there site..........
Plug into iOS Creativity
Sonic Port makes it easy to connect your guitar or bass to your iOS device and start making music. Simply plug your instrument into the 1/4" guitar input, launch GarageBand, the free Line 6 Mobile POD app, or another CoreAudio app, and start playing. Pro specs—up to 24-bit/48kHz audio quality throughout, and 110dB dynamic range on the guitar input—translate to full, powerful guitar tones.
Sonic Port also transforms your iPod touch, iPhone or iPad into a complete mobile studio. Track keyboards, mixers, CD players and other iOS devices using the 1/8” stereo line input. Plug in your favorite headphones and hear your audio in stunning clarity. You can even connect powered studio monitors via the 1/4” mono/stereo guitar/line-level output.
