hey all, I am running a 2006 ampeg svt hlf with a 2006 ampeg cl. I also have a 2012 ampeg svt 7 pro. Last night while I was practicing, the cabinet started to make some weird crackling static noises. I went through some tests...changing out the speak-on cable, trying the cab with both heads (not at the same time) changed out cords and even tried two different basses. The cabinet made the same sounds with every test and would get louder as you turned the volume up. Then, after powering down the CL and connecting it back to the 7 pro, the noises went away. I have never had this issue with this cabinet before and for the rest of the night the noises didn't return. Any ideas here? Thanks in advance. Daniel T.
