Hey there, fellow guitar enthusiast! I totally get your frustration when it comes to that loud and screeching sound that happens when you turn off your guitar pickup. It can be quite alarming and definitely not the sound you were hoping for. But fear not, because I'm here to shed some light on this issue and help you troubleshoot it like a pro.
When you turn off your guitar pickup and hear that unpleasant noise, it's usually caused by a phenomenon called "pickup noise" or "pickup feedback." This occurs when the pickup, which is the device responsible for capturing the vibrations of your guitar strings and converting them into an electrical signal, picks up unwanted noise or interference from external sources.
So, why does this happen when you turn off the pickup? Well, when you switch off the pickup, it essentially becomes an open circuit. This means that instead of the pickup being grounded or connected to a signal path, it's left floating. This floating state makes the pickup extremely sensitive to any electromagnetic interference in its surroundings, such as fluorescent lights, computer monitors, or even nearby electronic devices.
The result? That annoying screeching sound that can make your ears cringe. But don't worry, there are a few things you can do to minimize or even eliminate this issue.
Firstly, make sure your guitar is properly shielded. Guitar manufacturers usually shield the internal cavities of the guitar with conductive material to reduce unwanted noise. However, over time, this shielding can deteriorate or become less effective. If you're experiencing pickup noise, it might be worth considering re-shielding your guitar or having it done by a professional.
Another solution is to use a noise gate pedal. A noise gate pedal acts as a gatekeeper for your guitar signal, allowing it to pass through when you're playing, but cutting off the signal when it falls below a certain threshold. This can help eliminate the pickup noise when you're not playing and provide a cleaner sound overall.
Additionally, using shorter cables and keeping your guitar away from sources of electromagnetic interference can also help reduce pickup noise. Sometimes, simply changing your playing position or angling your guitar away from certain sources of interference can make a significant difference.
Remember, every guitar is unique, and what works for one might not work for another. So, don't be afraid to experiment and find the solution that works best for you and your specific setup.
