i get the tube on. i get the leds lit up. i get sound through the in to the out if the input
level is up... but other than this, not a thing responds to anything i try.
i am inclined to believe that all of my issues must stem from one error or oversight that

zero issues. i am completely baffled and must be missing something right in front of my
