Guitar amplifier ground loop

Email: billy guitars. If your rig has more than one amp in it and you are experiencing excessive hum or buzzing then you may have a ground loop. A ground loop is an unwanted current in a conductor connecting two points that are supposed to be at the same potential, often ground, but are actually at different potentials. Ground loops can be detrimental to the intended operation of the electrical system.

Ground loops, hums and tube amps...


Are you currently having some trouble with guitar humming? In online forums, people who experienced this problem have observed one thing in common. Though it can be easily alleviated by simply touching the jack or wire or the control knobs , how troublesome could it be? So, why does your electric guitar hum? There are several reasons why your electric guitar hums. The most common, especially if the noise reduces when you touch metal parts of your guitar, is the problem with the ground loop.

Similarly, your amps, speakers, pedals, and other devices that are connected to your guitar can also contribute to the noise. Lastly, everything in your home or studio that utilizes electricity emits an electromagnetic field, which can contribute to the annoying noise and humming of your guitar. This usually occurs due to lack of grounding, which may be a result of bad wiring, soldering, or the guitarist needs to have proper earthing.

It was observed even before that the guitar hums stop when the jack or the strings are touched. Hence, manufacturers soldered a wire on the bridge. When the player touches the strings or any grounded part of the guitar, the noise will immediately be suppressed. Though guitar hums just go away whenever you touch any metal part of your guitar, there are more effective ways to eliminate them.

The humming could be because of poor wiring or soldering. So, one best way to get rid of it is to check the wiring inside your guitar and see if they are properly soldered. Yet, if you are in doubt, what you can do is to do shielding in every component of your guitar cavity.

However, in order to prevent future issues with humming, you need to do this. The shield will prevent interference between the signal of your guitar and all the electronic devices around you. This means, instead of merely soldering the components together, they are now connected by one shield. Usually, the shielding used is copper foil. Another way is to get a noise suppressor.

However, before adding either of these two, know that they may somehow impact the sound output you will get. Hence, you must know what and how to use them to get a wonderful output without noise. There are instances that even if you touch the jack or the strings, the guitar noise increases, or it becomes worse. This is becoming serious, and you really need to have a look at it or bring it to someone who can troubleshoot the problem for you.

Here are a few ways to get into the root cause of the unwanted noise generated. Check out these two examples of guitar hum. The first one is 60Hz hum, which is usually caused by the electronic devices and cables around. The second one has Hz, which is usually generated by the ground loop problems. If you get this hum, then, you need to seriously do something with your guitar cavity components.

The common reason for this is the gain pedal or your amp is set to high gain. If you are playing at high gain, chances are the noise will be amplified. Try lowering the gain of your amp, or you can use either a noise gate or noise suppressor pedal. Determine what causes the humming. If, indeed, this is caused by the ground loop, proper soldering or even shielding the components of your guitar can save you.

Ground Loop Isolator


Some people might try to break the ground connection by cutting the grounding pin in the connector, using cheater plug, cutting the ground wire in equipment, taping over the grounding connector etc. Do not do this. Removing the ground connection isn't right. It is against electrical safety regulations and potentially very dangerous. Removing ground connection can defeat the actions of your noise filter or spike protectors inside the equipments. If the ground connection is cut then a fault in the isulation inside equipment will cause dangerous voltages to the equipment case instead of burning a fuse. Removing the ground connection from the equipments which have it is dangerous, against electronic safety regulations and you risk damaging your equipment. Running without a power ground will not automatically electrocute you but will make this much more propable if something goes wrong in your system.
