Factory-wound Fender pickups which are out of phase can be readily identified by their lead-in wires -- yellow and black, with cloth push-back insulation. These are typically the middle pickups of a matched set.

Devils advocate here Arjay.
I think RWRP are signified that way but a true out of phase pickup will have either RW or RP but not both.
I have found mixing SCNs with std Fender pickups will create an out of phase issue.
Academic of course and it sounds like the OP has something else going on.
Does the issue follow the pickup i.e. when it is moved to other positions? :D

I concur. I believe there's a wiring issue afoot.

Hi :)

what do you mean by "OP"

On my 3 pickups wires are black and white with cloth push-back insulation.

Do you think I should invert wires on the middle or neck one ?

OP original poster i.e. you
From what you describe prob not a phase issue.
In the neck mid position try tapping the poles lightly with a metal screw driver.
Does one pickup sound considerably louder than the other? How do they compare to the mid and bridge position.
Try swapping the pickups around ... you can do this by rewiring them on the switch , remove the tone jumper on the switch to eliminate the tone controls from the equation. As you can see the process will be one of eliminating possibilities e.g. is the problem the switch, the pickups, your wiring , pickup height etc
If you know how to use a meter use this as an aid for checking expected resistance values :D

So before you installed this new pick up in the neck position did you have the same issue in the 2/4 position? or Did you start w/ a fat 50's set and install the cs69 and the new pup at the same time and not have a reference for each pup that was changed?
You may have to go back to the original middle position pickup to eliminate your issue.
If it were me, I would put the cs69 in the neck position and use your original pup in the middle position.

I would ask how does your new pup compare to your original pup, same/close DCR, do they look alike-bobbin/poles/bevel/wire/etc. Return if possible your ebay bought pup and keep searching for what you want keeping in mind the middle position should be RWRP or you may have polarity issues w/ position 2/4.

+1

A marginal solder joint or two could very well be responsible for the problem.

@jimmy_james :

Ok for the OP LOL :mrgreen:
When I touch the poles of the pickups with a screw driver they sound equal.
I will try to swp the pickups this weekend to see if something change.

A new detail: today I noticed that the only position where the sound is clean (without hum) is the intermediate bridge+middle. I do not know if it means anything...

@sfceric64 :

I installed all pickups at the same time.
I bought these 3 pickups with a precise idea of ​​where I wanted to put them, so I do not want to swap them ... I prefer to change the one I was sold as 57/62 and find another one more suited ...:)

@Retroverbial :
I note it and I will track the marginal solder joints :wink:

Thanks to you all:D

ok something funny going on. As Arjay mentioned additional resistance could account for a level drop.
What resistance values do you get across the vol pot in all positions.
It should be approx. 6K in the std 3 and half that in positions 2 and 4
By your description you have said you do not think the front pickup is out of phase i.e. not sounding thin just sounding lower level.
No hum in bridge/ mid means probably RWRP in the mid pickup but if the front pickup was "normal" then you would expect no hum in the neck /mid position.
Check the magnetic polarity of all pickups with a compass or similar ...the bridge and neck should be one way and the mid another if we are dealing with a std scenario with a RWRP mid pickup. :D

Its really this simple:

If one doesn't attract the other two then you don't have a RWRP pickup.
Based on your statement about the middle/bridge being quite, I would guess maybe the pup you have in the bridge position is RWRP.

The OP indicated that it's a Fat 50's pickup. If that be the case and it's RW/RP, it would have the yellow and black lead-in wires.

Hello,

well, I disassembled the guitar and looked in detail the pickups and what was to happen happened, I have a micro rwrp. What is a shame is that it is the fat 50 (the one that is mounted in bridge).

I recapitulate :
I bought used 3 mics, a Fat 50 bridge, a CS 69 and a 57/62.
On arrival I have a 57/62 with a fanciful resistance (so I do not know what model it may be), a fat 50 which is rwrp (which means that it is not a bridge I was sold but a middle) and finally a CS 69 which seems to be authentic.
1 good on 3 ... some would say it could be worse.
Conclusion: Never again I buy microphones without reference of occasion.

Finally, I was so annoyed that I put everything back in the logical sense, despite what I wanted at first.
I have not yet made the adjustments but the distribution of the sounds seems more coherent and there is no hum at the intermediate positions.

Well at least now you have something playable, not configured the way you wanted but playable. We have all generally made a bad purchase at some point while trying to execute a plan, it happens.
Do your best to get your money back or adjust your plan, you'll get what you want eventually.

Well you could also put the 69 in the neck position and the other unknown pickup in the bridge ...
None of this really explains the drop in volume in the neck mid position though only the reason why the mid bridge had no hum but the neck mid did :D

@sfceric64 :
yes it's a guitaristic life lesson ! :mrgreen:

@jimmy_james :
Yes it's what I did, the unknown pickup in bridge position, the fat 50 in middle position and the 69 in neck position.
Ther is no more drop in volume, the sound is well balanced between the different pickups.
The bridge pickup sound a little arsh but I think it's his style. Maybe with a small height adjustment...
