Before you do anything. It's best to understand what your Les Paul controls are meant to be.
I am assuming a standard lespaul, which is 1 selector switch, 2 vol and 2 tone controls.
The selector is a 3-way switch, which switch on either pickup or mix both pickups together (centre position).
The bottom 2 sets of volume and tone is wired to each of the 2 pickups, so you can set the pickups output individually. (ie. one set to one pickup)
The trick is when you selector both pickup together (centre position). Then all the pots will afffect the output. The 2 volume pots are used as blend mode, either one is set zero the output will be zero, so both must set up some way to blend in the 2 pickups signal. This is because both pots are activated and the both output are joined, so if one control is turn to zero (ground), the whole signal is already short to ground.
Similar thing for the tone pot, either one set to zero, the output will cut the highs totally, both set to zero should cut more highs. It may feel funny in the beginning, but you should get used to it to learn to utilise this mode.
