Amp buzzing when using distortion

Hi.

Can you check for a buzz on other amps using your guitar?

Do you get the buzzing sound when using a humbucker pickup (if you got one)?

If so, it could be the grounding on your amp. check the electric cable for 3 pins and make sure they are in place.

also you may want to check the rig on different locations - it could be some sort of electric noise from a monitor\lamp that buzz.

 (the buzz exist on the clean mode as well, you just don't hear it. when you turn on the distortion it amplify the sound including the buzz)

try this :

1. unplug the cable from your guitar

2. apply the distortion

3. if the noise stopped, it's you'r guitar fault

4. if it still noising, pull the guitar-cable out of the amp.

5. if the noise stopped, it's you'r cable fault

6. if it still noising, check the power cord, it may have faulty ground connector
