Ok, so I just installed the emg 81tw and 89 on my g-400. I followed the wiring diagram off emg's site for 2 volume and 1 tone. I wired it up and now its gone really weird.

For starters, when I switch pickups it has no effect it sounds the same. When I use my push pull knobs, no effect. Hell even the volume controls do absolutely nothing, no volume loss when turned down, tone control does nothing. I am using a new Panasonic battery, is that the problem do they need Duracell or something? Bad switch? It is very weird, its like Its wired but its bypassing all the controls or something.

Edit: Sounds like the tone knob is always at zero.

Sorry don't have a camera right now, and the diagram is a pdf so I can't really post it.

Don't have a camera at the moment. Any idea where the problem could be? Or do they sound this bad. They sound very crappy also, very dark sounding.

Yeah, you messed up the wiring. Question is ... where?

haha just a thought. Is it possible that the battery is touching all the pots and some wire connections and is messing up the signal? batteries are made of metal after all.

Hmm i don't see how that would happen seeing as everything apart from the terminals is non-conductive and the terminals are plugged in to the battery recepticle which is covered by plastic or some sort of weird vinyl thing. If it was that however it would be pretty easy to test by just seperating out the battery from the electronics using say a bit of foam or whatever.

As SYK says though, it is pretty much impossible for us to help unless you have pics so you'll either have to get a camera or take another look at the electronics and the diagram and figure it out for yourself ?

Did you wire the pups to the right pot terminals if they are reversed or on the wrong terminal it will bypass the sound straight to the output........or so thats whats happened to me in times like these when I'm confused and pissed off a 3:00 in the morning cause my pups are bypassing my pots..........i'm throwing my best electrical knowlege here.........i'm a little ashamed of that.

Edit: Also listen to SYK he knows his stuff and its almost mandatory to show pics in the GB&C.

nope that's not really true, if you reverse them then the volume control is simply reversed. That's what i did by accident on my guitar and the volume works fine just the wrong way round lol. The volume would not have any effect (or it would just act like a weak tone control) if the 3rd terminal is not connected to ground.

Wait i forgot to elaborate if he acidentially wired the live to the correct terminals and did not ground the pot to its self by bending the terminal tab into itsself and soldering it there....You wrote that already.......damn.......thats what I remeber almost smashing my guitar for........I'm going to bed I need sleep and i'm not coherent when i'm sleepy so eddie you might be right that might what i did that caused that and TS sould look into that its a common mistake in my experience.......for me i mean.

This may be of no use but check that the cap leads are not accidentally touching a signal wire where there not supposed to. I had a problem with my wiring that the tone was like constantly 0, I checked and the cap lead was touching the wire from the volume pot to the tone and sending all the high frequencies to ground . Wrapped the leads in electrical tape to stop that happening and it was fine.

Although the other stuff still needs fixing. If nothing is working like its supposed to, then I would recommend unwiring everything and starting from scratch, following the diagram meticulously. It's the best I say without pics for more experienced UGers to help. Sometimes its best to start again, and the whole thing shouldn't take too long (and even if it does, your guitar's worth it, right? )

Though this probably wouldn't matter too much, what are all the pots' values?
it's all just coming back

does it sound any different when you remove the battery

They're EMGs... they'll sound a lot different...well actually, they wont sound at all

And this is really futile without pics.

OK, the pots are 25k pots, I followed the diagram correctly. As some have said the best thing to do is rewire it again, be extra careful etc. Thanks for your help, I'll try the things you said.
