I just bought an Epifani 3x10. Pretty awsome. I noticed though that there is a crackling coming through the horn. I know its not any cables or anything like that. Its strange because its very random. It will be fine for several minutes then come back in again. It kind of sounds like if you were shaking a loose cable around but thats not it. I dont really know what it would be picking up becuase there is nothing around my amp that would cause the interference. Its does it when my bass isnt even plugged in so I have eliminated that also. Also, the volume does not effect it. So when the amp is turned up loud you dont hear it. Its strange though and is isolated to the horn. I already Emailed Epifani about it. Thanks for any help.
