Phase cancellation is what happens when two pickups interfere with each other’s frequency responses, and most people find the result to be “thin” or “hollow” sounding. So, what happens when single coil pickups are mis-matched? You will either get hum or phase cancellation. Splitting a humbucker will, of course, bring back the hum. When combined, you get a fat, meaty tone and no hum. The two coils have opposite wind and opposite polarity. Humbuckers all operate on this principle. This is why most Strat middle pickups and Tele neck pickups are what is known as reverse wind, reverse polarity, or RWRP for short. With a RWRP middle pickup in a Strat, for example, you will get hum cancelling in positions 2 and 4 on a 5-way switch. If one pickup is north polarity, top going, the other must be south polarity, top coming.

The key to a strong, full tone with hum cancelling is to combine single coil pickups that have both opposite phase and opposite polarity. Modern Fender guitars are typically wired in such a way. One interesting property of single coils is that depending on their phase and polarity, it may be possible for them to be hum cancelling when combined. Phase can either be “top coming” or “top going”, and polarity can either be “south” or “north.”Ī typical application of these principles is with single coil pickups. With both properties, there are only two options. Phase is the direction current travels through the pickup, and polarity is the direction of the magnetic field. These properties are called phase and polarity. The goal of this article is to make sure you wind up with chocolate and peanut butter, not chocolate and onions.Įvery pickup coil has two properties that affect how they will sound when they are combined with others. Even if they are delicious on their own, they might be disgusting when combined. Guitar pickups are like flavours of food. Everyone else, pay attention! This is important stuff, and it might save your sanity some day, or at least your tone. If you have only one pickup in your guitar, feel free to ignore this article and live your life unhampered by phase and polarity issues.
