I have two Spider Jam amps, 2010 and 2019, both running the same DSP 2.09/MCU 1.05 firmware, and neither one will format various brands of 2 GB SD cards. I just tried a "Transcend" brand but got no results. Spider Jam tells me it's "formatting. . ." but then I hear a POP and it's as if the on/off switch has been tripped. When I go to check what's on the SD card, there is nothing. Getting my late 2013 iMac to read it could pose another hurdle. I'm having the same problems as previous posts.
