This is a really weird situation. I walked across a carpet and then touched the volume knob on my 2.1 computer speakers to turn them down, but when I walked across the carpet I built up a static charge and when I touched the knob the charge jumped about a 1/4 of an inch and went into either the bass knob or volume knob. After that happened I heard a loud pop from the speakers and then they stopped working. I unplugged them and plugged them in and they started working again, but now the bass knob doesn't do anything, the speakers constantly pump out full bass. I have no clue what is wrong, I would have thought it would be the rheostat, but that should stand up to low current high voltage shouldn't it?
