*****I RESOLVED THE ISSUE WITH THE SD CARD****
First and foremost a BIG shout out to all who have posted on this blog. I called customer support at Line 6 and I have to say I was happy to see they did not try to rush me off the phone and they were concerned of my issue; but he said something that made me think and profound. He said the Spider Jam amp was "old technology". Just knowing that only a 2gb SD was the max you could us. I.e all ready told me that. However, regardless of the size of the SD card, if it's new it's to fast. My mom has SD cards from 2008-2010, all 512mb, 1gb ,and 2gb. That was the issue. 'old Technology" must be used. Kind of sucks knowing something so awesome I.e Spider Jam, is old technology and they did not continue it's awesomeness in other products except Pod's.
Save all files to the SD as WAV. files. Use Switch Convertor by NCH Software to convert your files to MP3. (before downloading change from mono and select stereo and select amplify, then select convert. Then ITunes, the transfer to iPhone, then rock-n-roll, impress friends.
To upload back tracks save them first as a Wav.file. I don't think the Spider Jam recognizes MP3 from an SD card like it should.
