Just got round to re wiring my epi les paul. It desparately needs it as when i bought it, it was in a right mess. Bad solder joints etc.

Quick question though, do all the ground symbols on a wiring diagram need to go to the bridge gorund wire?

Usually the grounds will all be connected to the back of 1 pot. But you can also run the grounds to a lug attached to the body that will ground the shielding.

you need to connect everything including the bridge to the back of your volume pot, dont forget to connect the third lug of the same pot (and the other volume pot) to its back. if the cavity isnt shielded you need to connect the back of all four pots to the master volume. then you send it to the jack's ground connection.

connect all your grounding wires, INCLUDING THE BRIDGE GROUND!!!! or your pickups wont do anything
