Hey guys.. Was wondering if anyone in here can help me figure this one out. I just bought a new cable for my guitar, a Planet Waves Custom Series 20ft. I figured it's a decent cable for the price... Anyways.. the problem... when I plug it into the guitar, it makes an ear-peircing screetching sound.. Anyone have a clue why? thanks in advance!!
There's probably a break in the cable. Do the ends unscrew? Unscrew each end and see if anything looks loose or disconnected. If not, send it back and get a replacement.
Have you made sure everything is turned off before plugging in?
