Introducing the N-Audio Guitar Pickup Phase Checker:

This compact yet highly effective device is tailor-made to help you determine the wire function of any humbucker or single pickup. It’s a must-have for luthiers, guitar repair shops, and DIY enthusiasts who require quick pickup phase detection.

While renowned companies like Seymour Duncan or DiMarzio offer manuals for connecting their pickups, many stock and unknown pickups demand an initial phase check. For instance, identifying four-wire humbuckers is crucial for matching pickup phases.

Fortunately, with this handy tester, you can swiftly assess the phase of both passive and active pickups, as well as verify the phase of guitar effects and identify open circuit pickups.

With the N-Audio Guitar Pickup Phase Checker, you can streamline pickup phase analysis and testing, allowing you to spend more time enjoying your guitar and less time troubleshooting. Together with the N-audio Magnetic Pole Detector, you will have everything for proper guitar pickup analysis.
