buzzing guitar amp (reposted)

MontanaSlim · #1 April 4th, 2006

My amp (Randall Rx 30w) is three months old and yesterday, it started giving off
this fairly loud continuous buzzing noise. Sure it gave off a hum before but nothing like this. It didn't matter what settings I used, clean, OD, any of the effects, I couldn't seem to get rid of the buzz. Very annoying.

But after turning it off and putting the guitar away, a few minutes later I plugged in and turned it back on and the buzz is now gone again.

Could this have anything to do with the guitar cord? I almost thought at one point that
moving the cord around had an effect on the buzzing.

I have to ask this dumb question also: Is it normal for movement of the guitar cord
to amplify like when the cord drops to the floor or slides around the floor, should the sound from these cord movements be amplified?? I know mine is.

I'd greatly appreciate any help and have mercy, it's my first amp.

Sounds like the shielding on the chord is done for. Try a new chord.

some cords are very cheaply put together, and as allthumbs says the shielding is not always done to the right specs, if thats the case it will buzz and hum to its hearts delight, had to change the cord here as it was really bad for noise pickup made my bass sound like i had distortion on all the time.

well it could either be a bad chord or a bad ground check both

I'd start with the chord too.

It's probably not the case here but I almost re-packed my new Roland 60 amp to return it because of buzzing, when I first attempted to use it. Fortunately I realized that I had powered it up through an extension chord to the electrical outlet. When I took the extension chord out of the setup and plugged the amp's chord directly into the outlet, Viola! No more buzz.

Har. You never know what is going to mess with your amps mojo.
