It’s either a result of the pickups you’re using, interference getting picked up by your guitar or a grounding issue. Thanks so much for your thoughts on this, Jim! At a gig the other night I had a buzz coming from the amp only when the volume pot (on the guitar) was turned down. The Guitar Effects Course gives you a complete overview of Noise Gates vs Noise Suppressors and how they impact your tone. For example if you have a Telecaster (which are typically noisy), changing the pickups can make it sound less like a Telecaster.

Q: Why Does My Amp Hum When The Guitar’s Volume Knob Is At Zero? While the ideal situation is to remove the noise at the source, adding one of these pedals can produce great results.

If it does make a difference, you know that’s part of the issue. When the player plucks the steel strings, they vibrate next to the magnet, producing a similar vibration in the magnet’s magnetic field, which in turn causes a varying current in the coil. A good way to divide and conquer is to turn the volume control(s). In the US electricity alternates at 60Hz (50Hz outside of the US) which is why this type of hum is usually called ’60 cycle’ hum. A well made and wired guitar shouldn’t really have a need for extra shielding. One of the downsides of playing with a high gain tone is the high gain can create and amplify noise. it has to be a common drain to be a buffer, it was one of our lab projects when doing classes of amps or it will be an amplifying ratio.
