amp maiking weird niose

stratman471 · 03-30-2008, 04:27 PM

I was jamming with a couple of buddies yesterday and suddenly my amp was making this terrible crunchy sound whenever i hit a note. I swapped my cable and it still made the sound. Then I re-soldered the connections on the input jack of my guitar, and that made no difference either. I'm thinking that it may be a bad speaker cone. Any ideas as to what the problem is? It's a Marshall MG-15CD and i have been using it for about 4.5 years if that helps. Thanks.

Got the same prob on my G30R CD.

Usually happens after 5-10 mins.

Have you got an answer yet?

Cheers.

Sounds to me like a speaker problem. Can you test it with another speaker?

Yeah, try to hook up an external speaker of the same impedance.
