How to stop sympathetic reverberations on guitar

Hey guys, I know that at the moment, this platform is very largely a political discourse platform, but I have a feeling that in time it may be the new youtube. I haven't seen too many other music related channels, so i figured maybe it wouldnt hurt to try. Subscribe for more videos on how to maintain and upkeep your guitar, music theory, and just music in general. I also do guitar lessons both in person and on skype for anyone interested. thanks for any support and comments. very glad to have a new platform.
