confessions of an anti- soldertition

Robert Herndon said:
Now, I have been asked if I can dupe the same out of phase tone on a single coil. That would require me to push out all the pole pieces and reverse their positions, No??? And if it can be accomplished with just reversing the wiring polarities, where would the effect be present in terms of switch positions????

I think that's why in a three single coil pickup setup, the middle pickup's coil is reversed wound and the pole magnets are flipped: RW/RP. So, with a 5-way selector, positions 2 and 4 will not only give the guitar some serious quack, but it will have hum cancelling properties.

Hmmmmmmmm.....
 
I took an "electronics engineering technician" course & diploma back in 1990 so I've had a lot of practice with soldering. We used solder back then that contained lead so you had to wash your hands after handling it. I think these days solder is mostly lead-free. Soldering is easy to do if you have the right tools and technique.

This Gibson has way more quack in the middle position than any Strat I have heard.....

Just a clarifying point...Reverse Wound/Reverse Polarity (RW/RP) is not done to put wanted signals out of phase. It is done to achieve Common Mode Rejection of induced hum. Now, of course, CMR is a phase-cancellation. But, the hum cancellation occurs because the hum is 180 degrees out of phase, thus the cancellation. However, the wanted signal is not placed out of phase by means of the RW/RP middle pickup.

The quack effect in a Strat that is achieved in positions 2 and 4 is a result of the summing of the signals from two pickups that are sensing vibrations at significantly different portions of the string, not because of the RW/RP setup.

Long before Fender began using the RW/RP middle pickup and when they were still using just a 3-Way switch, Strat players were nudging the switch into the “in-between” positions to create the bridge/middle and neck/middle combinations. They did this to get the quack from those positions. At that time, they would still have hum because the RW/RP middle pickup hadn’t been developed yet, but they still got the quack.

Excellent explanation and thanks, El Smitro… :yesway:

They called those in between positions “tweener” switch positions back in the day.

Here's a drawing I made depicting what I was trying to say.

Essentially, RW/RP works to cancel hum because the hum is induced externally and is not dependent on the magnetic polarity.


PickupPhase.jpg

One thing to keep in mind is that the illustration above presents the ideas of reverse winding and reverse polarity incrementally. First, the idea of just reverse winding is shown and the effect that would have in relation to the other pickup. Then, the concept of reversing the magnet is added to show the additional effect it would have.

In reality, the signal and hum in the RWRP pickup aren’t being flipped back and forth. Simply, the orientation of the winding and magnetic polarity of the RWRP pickup results in a phase relationship with the non-RWRP pickup whereby the signal is in phase and the hum is out of phase.

I merely presented the idea in an incremental, chronological fashion to help visualize the concept.

Gotta use lead solder. Just like the best go karts gotta have baby coach wheels.
It just melts and flows better.
Just dont use it for your house plumbing potable water.

Adrian, you must be purged of your anti-soldering bias, and then "reeducated".
Molten metal is even more fun than a Bag 'O Glass.

(Malcolm is watching a loop of this:

Soldering is a '"gateway drug"' and often leads to the '"hard stuff"': stick, tig and mig welding.
Ahh the smell of 7018 rods in the morning; smells like....Victory!!!
Damn its been Wayyy too long since I have struck an arc.
 
I very much agree jtcnj, gotta be lead/tin solder. It's all I've ever used. I did try the lead free crap that came with an effect kit, (GGG or BYOC) only used it for a couple of joins & grabbed my own out to used. I've used it regularly for over 3 decade, never washed my hands after (well, not directly from touching the solder), I just avoid breathing the fumes. Adrian, if you are trying to learn to solder with the lead free stuff, that right there is a big part of why your finding it difficult. Get yourself some good old fashioned rosin cored lead/tin solder to learn with. Much easier to get to flow well & "take" to the job, & unless whatever you're soldering is really oxidised, you won't need to use a flux. Oh, never use an acid flux for electronics soldering. Cheers
