An electric guitar is a complex instrument and cannot be used immediately after purchase. Even if you have purchased a branded item, still go for shielding, because a brand new tool will disappoint you with noise and background. After all, the achievement of drive lies through the amplification of the sound signal hundreds of times, which means that the effect of amplification of all the smallest interference will happen. Every musician should be able to do this kind of operation.
Instructions
Step 1
Prepare materials. You will need either metal self-adhesive foil or graphite in aerosol cans. These are all sold at hardware stores or in the marketplace. Keep in mind that graphite is not very convenient to work with, because during the spraying process at close range, it settles around the guitar, leaving dirty spots. It will be easier for you to work with foil, with the exception of those models that have turned narrow grooves for wires. It will be difficult for you to get there with the foil. Ideal: Shield all easily accessible surfaces with foil and covered parts with graphite.
Make sure you have everything you need before starting work. If you decide to change the wiring at the same time, then redraw the circuit with all the connections: wires, pickups, toggle switch, jack and tone controls, which will need to be completely removed.
Step 2
Remember that the screen must be solid, with no gaping gaps. Moreover, this screen must be connected to the "ground" of the tone block, because you will lose the whole point of shielding. Your goal is to create a reliable electromagnetic shield around the tone controls.
Step 3
Also process the covers of the tone block and the toggle switches. Make sure that the shield of each cover you replace is connected to the common shield and grounded.
Step 4
If, during the screening process, an aerosol can with graphite causes the formation of drips or splashes, then immediately wipe them off the outer varnished surface, because after the graphite dries, this will become much more difficult.
Step 5
If in the process of working with the foil it "sags" in the corner parts of your instrument, then the foil will appear during the guitar playing, like a membrane, will rattle and resonate strongly, supplying electromagnetic interference to the pickup. As a result, you will get an unpleasant sound. Therefore, make sure that the foil, even in the smallest areas, carefully adheres to the wood, does not bubble. In the extremely undesirable case of the appearance of "bubbles", pierce them with a needle, and re-glue the foil properly.
Step 6
After applying shielding to all internal parts of the instrument, wait for them to dry. Now put everything back together.
