So I just finished my bottlehead and the sound is working fine through both channels. If i bump the crack while it's on though, I get a crackling noise and sometimes the sound goes out completely. I got the sound back just from tapping on the side a few times which I'm totally confused by. My only thought was that maybe a connection is loose somewhere, but I looked everything over and things seem connected well. Also, where I tap crack doesn't make a difference, which makes it seem like the issue is something general and not a single section that isn't connected well. Any ideas would be greatly appreciated, thanks!
