[QUOTE="americannight, post: 8068312, member: 624648"] I'd suspect the gain pot on the amp is faulty because when you turn it the crackling problem is either better or worse (depending where on the dial that gain is set). I also work a lot of live sound/pro audio gigs and this happens a lot with mixing boards and any equipment that has a potentiometer on it, such as the gain on your amp. When this happens in a live setting we typically turn the equipment off and work the pot back and forth a few times all the way up and down. Sometimes this will clear it if it is a dirt or dust issue. If that doesn't fix it then you can either replace the pot or you can remove the pot and if it is the type that is open on the back or has a removable back then you can shoot electric contact cleaner in there to rejuvenate it. Replacing that part will require some knowledge of electronics and soldering, etc. Sometimes the internal contacts on those pots are just completely worn and the part needs to be replaced. [/QUOTE]
