Only problem is the people on the Internet couldn’t find the right size battery, and had to do some modifications which was a pain in the ass. But these batteries are perfect size. No modification needed and they work great. Plus you get a couple spares in case the thing goes dead again in the future. But now my line 6 G10 Relay is working perfectly again.
