Hello everyone. I just bought a Seymour Duncan hotrails pu for the bridge of my Mexican strat. I hooked it up the way the instructions said and the hum from the bridge position is gone Yay! only problem is that now there's a hum in the second setting (bridge/mid) where there shouldn't be. Can anyone help me?

Don't use that setting...

Ah, I love that joke, no matter how old it is.

What kind of hum is it? Might be a ground problem. Might be a polarizing or out of phase problem. Around what freq. is the hum?

That will happen. They way it worked in the original configuration was the single coils of the bridge and mid pu were wired in opposite directions, so they offset to eliminate hum. Now that you have two coils in the bridge position they no longer balance each other, so your second position will hum.

I don't think i have any equipment capable of determining the frequency of the hum bro.

How would i determine whether it was a ground issue or polarizing or out of phaze or none of the above? and if it was of the above what would i do about it?

I agree.

That's not true, man. Your ear. It's a great piece of equipment. Of course, you need to learn to differentiate, but it's just like learning the difference between musical notes.

If it has four cables, you can coil split it.

What exactly does that entail?

Imagine an actual humbucker. Splitting the coils would give you either the top or bottom coil depending on how you wired it.

If the pickup has 4 wires the other two can be used to split the Hot Rails at the 4th position and use the whole pickup in the 5th.

Would i attach those wires to the pickup selector and the volume pot respectively? or do i need some fancy shmancy switch? the instructions for the pu had a little digram about coil splitting but it had some wierd six pronged box shown and i was completly lost.

The box in the diagram is probably the switch.

There is a cool Wiring Only Thread in GBnC that I would suggest you read through. It will help a lot. It is probably on page 1 or 2. What kind of solder iron do you have?

The thing is that I think you need a switch with 5 contacts (a super switch) if you want 4 to have coil split and 5 to be the full humbucker.

A stock strat would have a switch with 3 contacts (with 2 & 4 being connected to two contacts next to it).
