im installing EMG 81/85, i replaced everything except the 3 way switch. the old wires are still on them. i know the white wires are for the neck and bridge pickup. red wire is for the middle pickup. but theres a black wire and i dont know whats its for. it used to be connected to the volume pot on a passive pickup.

do i need to use that wire on the 81/85 pot?

I'd assume it's the ground wire.

ohh, that makes sense.. so i dont need that wire...


I'm going from memory, but I think you'll still need the wire that goes from the pots to the switch, but not the one that grounds the pickups themselves since EMG pickups are internally grounded.

Only if you like the danger of electric shock.

Have fun!

this is from the manual.
"When installing EMG Active Pickups, DO NOT con nect
the bridge ground wire. This wire is usually soldered
to a volume or tone control casing and goes to the
bridge. This wire grounds the strings and uses them
and your body as a shield against hum and buzz. It
also creates a shock hazard. EMG Pickups are
shielded internally and DO NOT require string
grounding. This greatly reduces the possibility of
reverse polarity shock from microphones and other
equipment"

it only talks about the bridge ground wire, but not the switch ground wire. wierd
