Magnet Polarity Tester

...I can't live without...

I purchased two of the Magnet Polarity Testers. One for me and one for a friend of mine who is also a real luther. He taught me every thing I needed to know to be able to maintain my guitars. The one thing we could never figure out was the polarity of the pickups. Just because the color code of the wires is correct,it dosent allways work the way you wanted. The Magnet Polarity Tester is so simple to use, and no guessing if the Polarity is correct. If you are going to do any rewireing or pickup changes, you will know if you got it right or not, with the Magnet Polarity Tester.
Thank You STEWMAC for a Great,easy to use product.

Very useful and works perfectly.

Smart and to the point. great tool! Thank you stew Mac. Very speedy standard shipping.

I recently replaced the bottom plate on a telecaster humbucker from the 70's. It had been bought on Ebay and someone had cut the feet that the screws go through to attach the pickup to the pickgaurd. I had seen a trade secrets article on replacing a base plate on a Gibson humbucker so I was brave enough to start.
When I was done the swap and the pickup was back together it sounded thin compared to other pickups of the same kind. The pickup measured as it should on my ohmmeter at 10.5 K. I had spotted the Magnetic Polarity tester in the catalog, read the information and ordered it. When it arrived I checked the pickup and found the polarity had been reversed. On these pickups the magnets are Cunife and are threaded. When I changed the plate I had mixed them up. Once I knew the polarity it was a simple fix. Thank you Stew Mac

Conveniently small and accurate, one of those I wish I had thought of that tool!

a plastic tube containing a little rounded magnet in two colors. Simple, effective and eminently useful.

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.

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!

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