Hi all, hoping someone can help out.. I have a Graphite S4000 headless bass.. serial no 158.. years a go someone modified the pots to be bass, treble and pick up blend.. as opposed to the original config of volume, pick-up blend and treble cut/boost.. ie now there's no volume pot now.. we're struggling to understand the wiring to fix it back to it's original set up.. if anyone has a wiring diagram.. maybe a photo of a working circuit or any pointers that'd be a great help, tried Status' site but no luck there.. thanks in advance!
