So I have an ashown superfly thats making wierd sounds. Its only when i turn it on, the meter that shows how much output its putting out peaks and crackles. It might pop 1,2 or 3 times then its fine. Recently I just turn the volume all the way down so when it pops its soft and it wont hurt the cab. The cab is a 4 ohm carvin 2x10, its got 150 watts more it can handle, so its a good fit. I'm just not sure what this sound is and if it can be fixed. Please help
