Polarity switches

  1. i've got one of these on my Peavey Firebass and i don't know what to make of it. it's set in the middle position now, just because that's the way it came. i don't wanna get zapped or anything. what's the deal with these things?

    geez :rolleyes:

    ya' can't go to the Peavey site and download the Firebass manual?

    c'mon man! ;)

  3. On the old amps, it determined which leg of the incoming AC the "Death Cap" was attached to. Put the switch in one position, completely let go of the strings of your bass, touch the strings with a finger and listen for a pop. Do it repeatedly. Now do the same thing for the other positions of the switch. In a properly wired and grounded outlet, middle will be optimum. If there is no ground, flipped to one side or the other will have no Pop, and the other side will have a Pop when you touch the strings.
