I recently purchased an Epiphone LP Classic and I think I may have a problem with the toggle switch. The owner's guide says that, when the switch is in the middle position, both pick ups are active. However, when mine is in the middle position, only the "treble" volume knob works. When I turn the treble the whole way down, I get no sound. Shouldn't I be able to adjust the volume for both pick ups?
Any help would be appreciated. It's a 45 minute drive to the shop I bought it at so I'd like to know if I actually have a problem before I drive out there.
Thanks

When the switch is in the middle both volume and tone knobs should work. If only one is working that's more than likely a problem with the switch. And yes it is normal for one volume control or the other to cut it out completely due to the way volume pots work by dumping the signal to ground. It eventually puts a full load on both pickups.
I assume since you didn't say otherwise, that if you switch between treble and rhythm they work fine individually.
Make sure they are both working by putting the switch in each position and tapping on the pickups with a coin to see which one is working in each each position with the amp turned on. Obviously in the middle you should get something from both pickups.

Mines wired the same way, don't worry about it.
The first time I heard a Beatles song was "Let It Be." Some little kid was singing along with it: "Let it pee, let it pee" and pretending he was taking a leak. Hey, that's what happened, OK?-some guy

Turning either volume all the way down should kill all sound.

Thanks all. Very helpful.
Also, sorry about the double post. I tried to delete my first one but couldn't figure out how.

do you have 2 humbuckers or 3 on your lp?

I asked the same exact question on the Epiphone forum. Thought I had a problem.
this is one of the replies I got
This is the way Epiphone wires their pickups. In the middle position turning either volume pot all the way down will kill any output. There are other wiring methods that can overcome this if it is a problem for you.
Take a look here for some suggestions.

Does your rhythm volume control do anything in the middle position?

Rockerman, I have 2 humbuckers.
Thanks to everyone's replies, I think I've got it figured out. You were all correct when you said that when either knob is turned the whole way down, it kills all sound. I did some experimenting last night and, when in the middle position, both pick ups are active as long as I'm sending some volume to both of them.
Thanks again.

Glad to hear that. Then everything is working as designed.
