I have an Epiphone Les Paul Custom Silverburst, and it's pretty new and has worked great until now. It seems my bridge pickup lost tone and volume for some reason. My volume and tone knobs are cranked and my amp is on overdrive, but whenever I switch to my bridge pickup it sounds very quiet, almost like it's on clean instead of overdrive. Any ideas?

Sounds like perhaps a Les Paul Special II, but more detail is needed to say for sure. There was a lot of variation in their Les Paul models. Posting a photo of both sides and the headstock is best.

-Has the guitar any binding, and what colour?
-Is the back of the guitar white or all black?
-Exactly what is on the front of the headstock, 'Epiphone', the 4-diamond logo, anything else?
.

I believe the top front is volume for the front/neck pickup...the top rear is for the rear/bridge pickup and the other two are tone knobs for the front and rear pickups.

If you are on a limited budget then get a standard Epiphone Les Paul. The Custom is not much better. If you have a little more to spend then I recommend getting a new or used Gibson Les Paul Studio.

Narrowing down which guitar to buy is completely opinion-based. You need to try multiple guitars to find one you like best since they all feel a little different.

Unless you are wanting to use the Nanomag, I'd just get it taken out of the signal. You should be able to bypass it anyways.

The volume is a common problem ... Search for wiring diagrams for your guitar to find a better wiring. Or take it to a guitar repair centre to have it fixed.

To tell which pickups are selected with the switch if it doesn't have the little plate telling you, Turn one volume down and flick the switch one way so you can hear just one pickup.

Two ways of telling which one it is picking up ... A toppy tone is the one nearest the bridge ... a bassy tone is the neck pickup ... The middle selection on the switch is both coils selected ... If you cant tell by tone ... Tap the pick up and you'll soon hear which one you have selected.

google your problem. i have found scematics on everything. i'm currenly changing out the pickups on my les paul, and saw the diagram on your soldering setup. i've done these myself. i was a little worried at first, but it turned out to be pretty easy. good luck, scott

You wont need new tone caps and the wiring will not need to be replaced even if you are installing new pickups.

This is exactly how any 2 pickup, 2 volume, 2 tone, three way switch guitar would be wired from the factory. Best of luck!

i have an old sg, and this happened to me too. the repair guy told me that inside the p/u, the windings were broken, resulting in a lower output. go on e-bay, and look up a neck pos. humbucker. there everywhere. or do yourself a favor, and do what i did. i have an epi. flying v, and epi. les paul. on e-bay, i bought gibson 57 classics. i put these in both my guitars, and i now have great sounding guitars. you will not belive the difference. good luck, scott

The controls should be setup in pairs (as long as the electronics haven't been modified. The two closest to the pickups are the volumes and the other two are the tone controls. The top knob set should be your neck pickup and the bottom set is for the bridge.

Good luck!
