Example, why you should take meter/compass measurements of any new pup you get

[Jack_TriPpEr]

The used SD SH-1N ('59) I ordered arrived in the mail earlier today, and I got around to taking the basic measurements on it with a multimeter and compass just a little while ago. Boy I am glad I took the measurements before just installing it with assumptions about it having typical specs for an SD Neck position pup. I would have had out-of-phase issues and been wondering what the heck was going on. Turns out the pup is Reverse Wind, Reverse Polarity (RWRP). I can arrange my wiring scheme to accomodate for this now that I know that about the pup in advance.

Moral of the story: always take measurements on any pup you get before installing it.

Here's a tutorial video I have found to be invaluable in learning how to take those measurements:

I'd imagine it would cause issues had you not tested it! Thanks for the reminder, and cool pickup!

Makes sense. It was listed online as Used.

Does the “RP” on the label signify “reverse polarity”? As it’s a printed label, is it a shop floor custom?

Yes, the "RP" stands for Reverse Polarity. Also, I would have thought this was an OEM pickup, but with that label, shop floor custom is a very likely possibility

I wonder if it came out of an Ed Roman guitar.

Or you could have just seen the "RP" on the label....

I do love the black baseplate- my recent Custom Shop set has those.

So flip the mag and put the leads back on the right coils.

I always figured painted backs were a sure sign of OEM pickups; didn't know the Custom Shop made any that way.
Definitely a cool look.

Question - does reverse polarity necessarily imply it's reverse wound?
I would've thought most of the ones made for OEM use would simply have had the magnet flipped.

I have a 59N/PG+ set in one of my Fenders and it hadn't occurred to me the neck might be RW as well as RP.

My Perpetual burn came out of the box new wired backwards stuff happens. Figured it out and just swapped the color codes instead of sending it back..
