Please Help, So for instance fat 50's are RWRP so that position 2 and 4 are hum cancelling. I have two questions. 1 can you then say add a texas special to the neck and still recieve the position two hum cancelling? 2. Are there any other fender pickups with this attribute?

Thanks in advance...

Only the middle pickup in the Fat 50's set is RWRP -- just as with the Texas Specials set. Thus, a "mix and match" between the two sets is possible.

It's not about the pickups. It's about how they are wired. The middle pickup is soldered in reverse polarity, and this is called "RWRP".

So "soldering the pickups in reverse" also re-orients the polarity of the magnetic poles pieces?!?!?

Good luck with that!

Mebbe you can perfect cold fusion while you're at it.

:roll:

it's in my drawer. Wanna buy it? Mr Shell has a copy too.

The magnetic polarity and the wind direction of the pickup is the opposite to the other coils on the guitar. Should have been more clear with that. But it's still not "the pickup" which does it. It's the combination.

Correct. By itself the RWRP pickup will sound no different than a conventional Strat type. It's only when its output is summed together with that of a standard pickup that the "magic quack" (and the hum-cancelling) occurs.

Quack! Quack!

Can I add a question here? I read that the lower you set the middle p/u compared to the other two, the more quack you get. Is that correct as a rule of thumb?

Cheers

Great question.

To tell the truth, I'm not sure.

I know I have my Fat 50's adjusted relatively low -- around 2.5mm from the strings on the treble side, 3.5mm for the wound strings. Sounds awesome.

I think that question is easily answered with a little experimentation. If you are talking about the "quack" you get in positions 2 & 4, I think that what you will find is that the relative output contribution of each pickup to the signal is what determines the "quackiness". For example, unless the pickups have calibrated outputs (some do), the neck position will always be the loudest due to the fact that it is closest to the area of maximum string vibration. That is followed by the middle pickup, then the bridge as it is furthest from the area of max string vibration. So, what do you do? Well, typically you adjust the neck pickup to be furthest from the strings, the bridge pickup to be closest, and the middle pickup somewhere in the, well, middle.

Ok, so now you have the relative outputs of each pickup as close to being equal as you can. Are they "quacky" enough in positions 2 & 4? If not, adjusting the height of the middle pickup will alter the relative output contribution of the two pickups in the pair. Lowering the middle pickup will increase the bridge output contribution in that pair, and the neck output contribution in that pair. A slight change in middle pickup height usually results in a significant change in "quack".

In my case, I have all three pickups adjusted flat (no tilt towards the treble side) with the neck pickup at 11/64" from the "E" strings, the middle at 12/64" from the "E" strings, and the bridge at 10/64" from the "E" strings. In my case, I also found that the middle pickup was inherently slightly louder than the neck and bridge due to the fact the neck and bridge have tone circuits attached to them while the middle runs wide open. I get great quack in positions 2 & 4 and the individual pickup output in the other switch selections is reasonably well balanced with no significant volume changes between pickups.

Forgot to mention, but my pickups are Fender SCNs. I hope that lengthy and somewhat boring explanation made some sense.

Makes sense to me, Bill.

Thanks!

It really became apparent to me when I switched from nickle plated steel strings to pure nickle strings. Previously, I had all the pickups set to 12/64" and the quack in positions 2 & 4 was awful. I actually coinsidered going to a 3-way switch. When I switched string type, I noticed immediately that the bass/treble tonal balance, as well as the balance between pickups was different (I actually tried pure nickle strings shortly after getting my Strat and noticed this effect, but was too dumb to know what to do about it). The loudness difference with the middle pickup was immediately noticable. I found that when I got the three pickups rebalanced, the quack in 2 & 4 improved noticably. Also, because the bass response of a pure nickle wound string is less than that of a nickle plated steel wound string, setting the pickups flat improved the tonal balance, and also the quack.

This is a perfect example of why the advice to "use your ears" is the best advice when someone asks how to adjust their pickups. But since I am an engineer, I also have to have a number, hence the settings I gave in my earlier post. :lol:

Thank you all very much for this comprehensive reply. Much fiddling for me to do :idea:
