The Theory Behind Using Dummy Magnetic Coils In Your Vintage Guitars
by Dianne Crane
The idea of using dummy magnetic coils in older guitars is not a new one. In fact it's one that has been around since people first started plugging them in. It is an old idea that has gained growing popularity with the younger crowd because of the ease they are to install and the effect on the sound that they have.
The dummy pickup is generally just a copper coil of wire connected either in series or wired in parallel with any existing pickups inside the guitar. It has no real magnet, and will not create any field for the steel strings to vibrate inside. What is actually does is take a signal from an existing pick up, it then turns it 180 degrees. The effect of this is removing a massive amount of the dreaded 60 cycle hum which most single coil pickups always have.
The larger you make the coil size the less resistance that is needed to stop the hum from happening. The coil can be a simple air coil, or it can have a non-magnetic ferrous rod in the center of it. A good resistance range to shoot for is around 50 to 80 percent of the single coil you are using. This is not rocket science and most anything will work with a little tweaking after installation.
One of the simplest ways to achieve this effect is by using a cheap single pickup and removing the magnet attached at the bottom. Very inexpensive pickups can be bought for less than $20.00 from online stores and hometown music stores. Just remove the bottom magnet and you have made your coil ready to be wired in.
What matters the most when wiring it up is the direction of of the wire winding of the dummy and real coil. It is possible to wire the dummy in parallel where each one has a single lead wire to the input switch or volume pot. It is also possible to wire it in series where the lead from the real one goes to the volume pot and the lead from the dummy goes to the ground. The other two leads are then connected and this puts them in series.
There are numerous different variations with applying setup. With the numerous different combinations you also have the possibility to make many different sounds. The general idea is first to decide what sound type you are aiming for and move toward that sound.
The hum cancellation is just a wonderful side effect of going with this type of set up in your guitar. This setup is often used for production blues guitars. Some notable users of this type of system are Eric Clapton and B. B. King.
Before dismantling your guitar, research it and understand the basic science of pickups and the theories behind a dummy <A href="http://www.lancocontacts.com">magnetic coils</A>. It will take some time to fine tune the instrument with this home modification. Still, if you truly desire a custom blues sound and honestly dislike that annoying hum you always get with a single pickup, this may be the item for you.
