EMG wiring help!

Hey everyone!

Im trying to put EMGs in my RG 1570 (which has been a ginormous pain in the ass lol, had to sand the pickup cavities just to get them to fit), I bought it used and the old jack was pretty busted so I got a new one.


This is what the jack looks like,



I found this which looks similar


and also on the diagram it states R S T and I have no idea what these mean lol

Re: EMG wiring help!

T = tip
R = ring
S = sleeve
of the jack plug

Just cut the long contact shorter with a plier if possible.

Cheers

Re: EMG wiring help!

Isn't the long contact one of the three? If there are four you have a stereo jack with two tips.
Otherwise cut the long contact shorter and use it as the "s" in your diagram. Just make sure that the cables or contacts do not touch each other.

Re: EMG wiring help!

I foudn this on anotehr forum

"
Thanks for the tip.
I sorted it out later so if anyone else need help with this it should be wired like this:

Signal - the shortest contact
battery - medium long contact
Earth (ground) - ring contact.
Longest contact remains free."

not sure if its helpful though

Re: EMG wiring help!

so im thinking

The long contact = sleeve?
A round/ring contact = ring?
A square contact thats short = tip?
A square contact thats taller

So would I jsut leave one of the square contacts?

Re: EMG wiring help!

Yes, it should be: Tip is the signal and sleeve, the longest contact is ground.
As the cable when plugged in will shorten shaft and rings it does not matter which ring you use. I have never installed active pickups, but I guess using battery negative on the ring will power the circuit on when the cable gets plugged in.
Not sure about round and square.

Re: EMG wiring help!

Awesome thanks! I tried soldering the long contact to the sleeve position, the round/ring contact to the ring position, and the square contact thats taller to the tip position. If I shove the cable all the way in nothing happens (im not sure if setting the distances will change anything) but I can fidn th e sweet spot where I hear noise through my amp and touching the pickups or the volume/tone pot (havent put the knobs on yet) increases the pitch of the noise. Switching from various positions through the blade switch doesnt affect the tone or anything at all, doesnt even interrupt the noise. Does this mean theres a short somewhere or should I solder the tip to the other square contact?

Re: EMG wiring help!

I suggest using a multimeter. The long contact could also be only a ground connection for the housing. In that case I would have only added confusion and you would have been right with just cutting it. And you would have only a normal stereo jack with only one ring. Sorry in that case.
With a multimeter you will know exactly.
