Marshall MG 100 DFX Sound Problem

[foe mie]

Hi,

I had a problem with my amp. It has two type of sounds (loud and low). When I play, suddenly it turns to loud and it stays for a certain extension then turns back to low. It will repeatedly happens during the session. I did brought to the repair shop few times but they couldn't define the problem. Already give up with the problem. Can somebody help me who have an idea to solve this problem?

Cheers

It's most likely due to broken solder joints or dirty contacts in the controls.
