My name is Andrew and I have just got a Bass guitar for christmas. I am new to the bass guitar and some problems have just started arising. The model is an Ibanez GSR200 it is a good bass and so far I have been getting some good results from it. However when I play it some times down at the bridge of the bass there is a humming noise as the sting vibrates against metal. I would like to know if a ny one would be a ble to help me.
