Sometimes you need to know the polarity of your pickups. Like when you order a new single coil neck pickup and you want to make sure it will be in phase with the middle already in your guitar. Or you need a new Jazzmaster™ or P-90 or Jazz Bass or P &J Bass bridge pickup and want to get the noise cancellation in the middle switch position.
Well, we have got you covered! And unless you know your existing pickup's polarity for certain, you will probably want to get one of these kits.
The kit includes:
1 Super Accurate BA Compass (Well, accurate enough.) 1 Extra Cool Instruction Card 1 Awesome Swag Collection
