A beastly Ibanez 5 string bass in for an intermittent short circuit and fret buzz.  I traced the output issue to a bad 25k volume pot that needed to be replaced (see video below for the replacement).  As for the fret buzz, treble side fret ends 12-20 were playing it high and loose.  The inexpensive fix was to glue and clamp them back down.  Doing a fret level after they were locked back down would have further improved clean playing up the neck.
