I have been noticing heavy static noise when playing from my iPad Air and using the headphone jack directly into a Line 6 Spider Jam Amp CD/MP3 front Input. (See attached pic) I run my ESP M2 Deluxe guitar into an Apogee Jam interface, which then goes into the lightning port on the iPad Air. It usually starts up when I'm not playing anything on the guitar and just plugged in. Any help would be greatly appreciated! Thanks
