Ive posted a similar question before, but came up empty handed. Just searched the forum and couldnt exactly find an answer. I have a JHS little black buffer. Here is the prob. I turn my gear on. And ONLY the 1st 3 pedals ( Turbo tuner > BB > Shiba ) that are placed after it will pop like its gonna explode .. for about 10 minutes then it goes away and becomes dead quiet again. It just happens when I just turn the stuff on. Now I had this problem earlier when I had the polytune. I had read that many people with the polytune had the same thing happen ( thinking the problem was with the poly) . I now have a turbo tuner and was surprised when it did it again. Only with the polytune it would not stop. ] Is there something up with my buffer? Electricity? What could it be?
