Hello guys, I am having a bit of a problem with my alvarez 4 string electric bass. When I plug it into my amp, ibanez sw35, it makes a strange noise that sometimes goes away when I mess with the cable at basses input jack. After doing a little bit of research, the closest thing I can find that matches with this problem has something to do with the grounding wire. So my question is, if it is the ground wire within the bass then where is it located, or how can I recognize which one of the wires it is. Thanks in advance for the help.
The grounding wire is underneath the bridge.
If it goes away when you mess with the patch cord, Im guessing you need a new patch cord.
