Oh wow, close call, the email we got from Yamaha/Line6 was really confusing and misleading. I'm glad I read more carefully and I didn't destroy the USB power cord that came with my G10 unit.
I'm curious, what the heck was the purpose of the recalled "Line 6 Relay G10T USB Charging Cable" anyways? It has USB on on end but some kind of 1/8" female mini plug on the other end. What did that female end even attach to on a G10? Doesn't make sense why anyone would have paid extra for this "accessory".
