Another GFS question...

Hello all

 

I am replacing the stock pups on my Dot with GFS 59s which arrived from the good ol' US of A today. I am "cheating" by using the existing wiring to the pots and was wondering if anyone knows how the colours match up.

 

thanks

With Seymour Duncan Black wire is hot/+, Green + bare wire is ground[Edit: red and white stay twisted together unless you want to split or phase]

 

On my Epi the black cable[Edit: or blue] is not coding signal but identifies the Bridge PU, the white cable is hot/+, twisted bare wire is ground.

Same with neck PU. Red cable identifies the Neck PU. White is hot/+, bare is ground.

Didn't you get the wiring diagram with your pickups? Every GFS pickup I've ever bought had the wiring diagram in the package.

 

I did indeed....

 

Black = Ground

Silver shield = Ground

Green = +

 

Connect Red to white - No contact for humbucker.

 

I need to know what colours the Epiphone wires are in relation to this..... Are they the same?

The SD colour code will work for GFS, but as Ricochet mentioned, with

SD's the hot (start of winding for N coil) is BLK. With GFS, it's Black, but

they show it as going to GND and the GRN (start of winding on the S coil)

as the hot. Now it shouldn't make too much difference, unless you're

coil splitting with the red/white connected to a push-pull and a phase

switch..then it appears to.

 

 

As far as the Asian EPI OEM p_ups, the ones I removed are only two wire,

with white being the signal (hot) and shield being GND (pot case).

They seem to use a colour code on the wire jacket to signify either Neck (Red)

or Bridge (Blue).

Ok, so on the GFS, is Green +, or is it the black?

It really doesn't matter. The + is just a symbol. It is a audio frequency that

comes out on those wires and polarity doesn't matter (phasing does but

that only applies to 4 wire configurations).

 

You can connect either colour to the volume pot and and still get the sound.

 

I could get into electronic specifics of the coils, but this would

add more confusion as Ricochet mentions in his post..so just do it as you

have decided for two wire connection. Just consider one of the wires as

an extra ground.

All done!!!

 

I can't believe the difference those GFS 59's make! Especially in the neck pup. I'd post some pics, but it looks exactly the same.

 

One thing I noticed though is that the bridge GFS pup ring was on the wrong way when I got it out of the box. The thicker side should point towards the bridge, but this was the other way round. I ended up using the existing rings as they looked better anyway.

 

Thank you so much for all of your help on this everyone.
