Guitar Pickup Phase Checker Rev.2
Checking your guitar pickup phase has never been so simple! This handy tool lets you quickly check the phase. It’s perfect when upgrading or wiring your guitar. The new Rev.2 version features an improved detection circuit and lower power consumption, making it even more efficient and reliable.
Introducing the N-Audio Guitar Pickup Phase Checker:
This compact tool helps you quickly identify the wiring and phase of any guitar pickup – whether it’s a humbucker or a single coil. It’s perfect for luthiers, guitar techs, and DIY enthusiasts who want fast, accurate results without guesswork.
While well-known brands like Seymour Duncan or DiMarzio provide wiring diagrams, many stock or unbranded pickups don’t. This tester makes it easy to determine the wiring on 2-, 3-, or 4-conductor pickups and match their phases properly.
You can also use it to test both passive and active pickups, check the output phase of effects pedals, and detect pickups with open circuits. Together with the N-audio Magnetic Pole Detector, it gives you a complete solution for pickup testing and analysis.

Key Features:
- Effortless Pickup Phase Checking: Perform non-invasive phase checks directly on the guitar without the need for desoldering or disassembly.
- Open Circuit Detection: Easily identify open-circuit pickups.
- Universal Compatibility: Works with all types of single or humbucker pickups, whether passive or active.
- Wire Identification: Quickly identify the wiring of unknown 2, 3, or 4-wire pickups, saving you time and hassle during installation or repair.
- Guitar Effects Pedal Phase Checking: Ensure the correct phase of your guitar effects pedals.
- Ultra-low current consumption
