Need help wiring guitar

Hey guys I got a new epi black beauty and I'm trying to install new bridge/neck pickups and rewiring it to be 3 volume pots and 1 master tone control. Im using the guides here:

Here is what I have so far. I THINK I did most of it right but I'm not sure about how to ground everything

Everything gets grounded to the backs of the pots including the braided outer sleeve from the pickup wires.

You want the wire from the tailpiece (the red one in this pic) to go here too, as well as a wire (yellow sleeved wires in this pic) connecting all four pot backs together.

2 things ...make sure your pots are turned all the way to one side or the other before soldering so you don't overheat them and get a dead spot....and don't forget to ground the switch...alot of people overlook that. Other than that just follow the schematic exactly.

ok so I need to connect the back of the pots... And for the switch, well, I think I did it right. But my switch has a total of 6 metal points coming out of it and I'm not sure which side is which. When I desoldered everything it all appeared to be grounded on the left side so that's what I am going off of. To ground it I used a long red wire to go from the switch to the back of one of the pots is that all right?

 

And for the metal shields do I just get a wire to go from them to the pots? lastly, does it matter if anything is touching in the cavity?

 

thanks guys

Well, that's not a standard switch, it's a special one unique to the Black Beauty, designed to give you Lead/Lead plus Middle/Rhythm selections. However if I'm not mistaken you can use it as a regular three-way by ignoring one of the contacts (that the middle pickup was connected to). It's pretty easy to see what these switches are doing since you can watch the contacts opening and closing as you move it around.

http://www.axiomatic-music.co.uk/acatalog/CircuitDiagrams.html The LP custom 3PUP drawing is what you are trying to do with a six terminal switch...you simply need to find the terminal layout for your particular switch. As you can see one terminal is unused in the 3 volume 1 tone drawing. If your still having trouble just meter out the switch. Part of your problem is the other drawing is showing a standard switch. Also the center leaf on the switchcraft is the switch ground. Best of luck!

hey thanks for that new wiring schematic. it seems to work a lot better than any of the other ones.

 

I'm almost 100% sure I've grounded everything, but there's still a lot of noise and when I touch the metal part of the cable running into the output jack of the guitar the noise lessens considerably. I'm guessing this is a grounding issue?

 

I put 1 sting on and gave it a little test so it CAN play, but there seems to be a ton of noise and when I use the master tone control the noise goes crazy.

It's kinda hard to tell without seeing it but it sure sounds like you have an issue with the string ground to the bridge/tail piece to me.

well the tailpiece ground and the output jack ground all all together.

 

Here are some pics

the ground is the black wire out on the left and it is soldered in with all the other grounds on the top left pot.

 

Also, the problem could be because of the selector switch which I still haven't completely figured out yet. BTW, the wires that aren't soldered to anything and are just sticking out - I have 1 extra wire in there and if they aren't the extra wire, its because I'm making mechanical connections to test it out before I go ahead and solder it all together.

hey guys umm... Sorry for bumping this but I really have no idea why the output jack/tailpiece isn't grounding right. Any suggestions? Or perhaps there is a forum/website devoted to these kinds of things?

 

Please don't take this the wrong way but it's kinda hard to see through all the spaghetti...from what I can see looks like you only have 2 of the pot backs grounded to each other? You want all four tied together and then the string ground and output jack ground and switch ground too. Just nit picking, but I never use red wire for grounds it gets confusing to look at. If you always use black or green for grounds it's easier to keep things straight. I hope that helps.

well I agree its a bit of a mess, but the guitar has 3 pickups and it was pretty messy when I got in there to begin with.

 

Well, everything is grounded and the pot grounds are connected. I even tested it with the meter. The only thing that's a little weird is that the middle (stock) pickup and the output jack wires don't have a metal shield that needs grounding. Instead, they have two wires in one plastic shield. The second wire is also shielded with plastic and it just kinda sticks out. (I have them grounded but maybe they're part of the problem)

 

hmm I looked at it again and ya one of them doesn't appear to be grounded to the others. But when I use the meter is says there is a connection?

 

still, I had the 4 together before and I still got the buzz from the tailpiece and the output

 

also I was messing around and it seems like you can use the two wires interchangably. so I don't know which one is the ground and which one isnt

Okay, the plastic is not a shield; it's just insulation. Both those wires must have a shield somewhere, look for a multi-stranded silver wire. If you haven't grounded this, you're going to have problems.

 

Otherwise it sounds like there's something bogus with your tone control wiring or else maybe you have the output jack wired backwards?

 

Just re-wired an Epi LP Standard last night, here's what it looks like once you clear out the original spaghetti. I only kept the wire that goes to the switch (red and yellow) and then returns (white) for the output. It's hard to see but the white wire is connected to the braided wire that goes to the jack...

ok thanks I'm pretty new to all this. Ya It'd be a lot easier if I had only 2 pickups or if I just wanted to keep it 2 tone/2 volume.

 

Here's the output jack wire. What do you think? which ones the ground?

Also, I'm still a bit unsure about the selector switch... should it affect the noise level much if its improperly wired over there?

 

ya I'm thinking the tone control might be messed up too.

the diagram im using is the 2nd to last one (the one right above the Jimmy Page one)

http://www.axiomatic-music.co.uk/acatalog/CircuitDiagrams.html

 

I don't know about how it all works so I've just been following the guide. The one I first posted didn't seem to work at all so I'm just sticking with this one I suppose.

The white insulated wire is the signal. The other is ground.

 

Hate to tell ya, but I think you need to strip all that spaghetti out of there and start from scratch. That's what I'd do. Even with the third pickup there's no reason for such a mess.

Please do! Ya I am thinking thats what I'm going to do. The thing is, I just want to make sure it works all right and then redo it. But ya it'd probably be easier to do if it was less messy.

 

Oh... the white one is the signal... lol. ok I had it all backwards then! gah
