Line6 support recommend I post here. I just received a SpiderJam amp and experienced difficulty with formatting the sd card using the wav,44100, mono set up. I am using a Fender g-dec3 30 amp that formats using MP3. Theirs seems to be more user friendly. Support said this jam format is somewhat old and there is no plan to change. On the forums this topic comes up and the cure seems to download a third party converter. Would it be possible by firmware update to include different formats? I do like the sound from the SJ bur simpler formatting would really improve this situation. I am probably over-simplifying this but it would seem to be a viable upgrade.
