HH, inner coils are not hum canceling

[Zheddar]

Charvel (owned by Fender) often have their stock Duncan neck pickups with a flipped magnet when running 2 humbuckers and a 4 pole super switch (in recent builds), and usually designate that with naming conventions such as "SH-2n RP".

That means euther the Pegasus or the Jazz has the magnet in an "already flipped" state.

Do you have a compass so you could verify?

this youtube video demos how to take that measurement w the compass. Btw, it also shows how to perform a lot of other worthwhile measurements on a pickup.

I don't have a polarity tester, but using the Full Shred that I took out of the guitar, I can determine that the polarities of the coils of the bridge and neck are opposite (held the same way, the full shred attracts to the bridge pickup and repels the neck pickup). FYI, slugs are the inner coils.

Wow, thanks for the cool insight Zheddar.

Ok, that could explain it. Assuming the SD Jazz pup that is currently in the Neck position of Grimm's Charvel came stock with that guitar.

Yep the neck pickup is still stock. The next time I change strings, I'll pull it and check if it says anything on the back about being reverse polarity.

Zheddar,

What you describe about one of two seymour duncan pups having a mag flip but without a reverse wind, when they are featured as stock pups in some guitar manufacturer's model, might also explain why member RexRemus found one of the pups in his SD Alpha / Omega set to unexpected have the same setup. I was assisting him last year in debugging why he couldn't get inner coilsplits to be hum-canceling like in this thread and the multimeter measurents revealed the odd setup. With your input, we may now have an answer WHY. AS the Alpha /Omega set is similar to the Charvel SD pups in that they are featured as the stock pups on PRS Mark Holcomb signature model.

So, just flipping the magnet without being reverse wound, you have to change the colors to wire the pickup 'backwards', right? When the pickup is truly reverse wound/reverse polarity, you wire it normally (I think). This is where I get all flipped around.

Correct
