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.

QC issue, but fully functional

The first one of these I received broke (black dot came off) within about 5 minutes. StewMac support apologized profusely and had a new one in my hands within a few days (which has been fine so far). Very handy little tool to have!

Work just as described!

This tool does just what it is advertised to do and does it well. I could have built my own out of a neo magnet, a small plastic tube, and some paint, but it would have cost me about the same and taken all that time! I really like that I can quickly test without having anything actually touch the pickup or pickup magnet...unlike the way I used to do it with a painted disk magnet.

Got business? Reduce Guesswork = more money!

If you own a small shop or any business, you HAVE to have this, it's that simple. This eliminates guesswork, which translates into less time wasted, which gives you more time to do more jobs, which gives you MORE MONEY EARNED. pays for itself the first pickup issue you get, and you'll get a few of them. Even for just a hobby, it makes your pickup experiments a quick success. You don't need this, you WANT this!

useful.

never, ever did i think i needed one of these. Its one of those little widgets that, once you've used it for the first time, wondered how you ever managed without it.

simple and easy

I use this on a lot of vintage guitars to see if they are north or south facing pickups. Surprising to see and fun to use.

Time Saving Tool

I repair pickups and wind new ones in my repair shop. This easy to use tool saves me time in determining south or north up. I even had a factory pickup that the magnet was installed in reverse to the intended specs. The guitar's tone was odd/out-of-phase and I checked the polarity first off to find the problem. This purchase has been an important shop aid for me.
