Disc-o-Tone Buzz When Plugged Into Amplifier

When I plug into my amp I get a loud hum / buzz that seems to drown out the strings. It goes away almost completely when I touch the cord going into the jack and it seems to go away a little bit when I touch the volume pot. 

For my pickup I purchased the Disc-o-Tone from C.B. Gitty:

From reading the forum it seems like I have a grounding issue but I thought the the Disc-o-Tone kit was grounded out of the box and ready to go? I've attached an image of the pickup from C.B. Gitty's site. Also, I am using a threaded rod for both the bridge and nut.

I bought a Fender Mustang 1 v.2 to use with this guitar. The sound coming through the amp itself seems very distorted with the hum / buzz. When I plug my headphones into the amp I can still hear the hum / buzz but the sound coming from the guitar sounds much clearer.

I've never played a CBG before or really any guitar so any help you all could give me would be greatly appreciated.

  • I'm with Dave. I've found flipping the plug often helps if it's and older amp without grounding plug. Otherwise, i've learned to ground the strings by a wire from the tailpiece or bridge metal to the back of the volume pot. Some ground to the ground on the jack, but i get better results from the back of the volume pot. If the hum/buzz goes away when you touch your strings or metal parts on the pots, then this will fix it.

  • sounds to me like it is a amplifier grounding problem. just a thought, but you might try turning the amp power plug over. I live in a older home and I have found that when the older houses were wired they were not always consistent in following polarity when they wired the outlets. have fun. DC
