Pickup rewinding specialist J.M. Rolph has noted, "How many times have you wired a pickup and found it's magnetically out of phase, with the same thin, low-powered sound as a pickup that's wired out of phase, even though the lead wires looked right?" By indicating the north or south magnetic orientation of a pickup's polepieces, this polarity tester can help you avoid the problem.

With a basic knowledge of vintage pickup magnet polarities (instructions are included), this tool is also a quick way to determine a pickup's authenticity.

A must have

I have used this on every guitar I've laid hands on since I got it. Great for pickup installations, can even help identify correct pickup polarity for vintage instruments.

Works Perfectly

Could a magnetic compass accomplish the same thing? Yes! But this is fast, easy to read, rugged and reasonably inexpensive. Small cylindrical size its unobtrusively in my tool pouch. Just the ticket!

A Must Have

If you work on or wind pickups you need this tool. If you don't know why, you shouldn't be working on pickups.

Magnetic Polarity Tester

Effective and small. I assume that white up and visible is north and not white down and attracted to the coil. Just a little ambiguous for me! Still, you can tell one pickup from another in an instant.

Neat little tool

Love this thing. I use it a lot when winding pickups to verify magnetic polarity, as well as for odd jobs like determining which coil to cut for hum canceling when combined with a single coil.

What is this pickup?

You know the brand, you know the DC Ohms resistance, but do you know whether the pickup is north or south. This will tell you quickly. No more installing to find that one or more is out of phase.
