Hello, As I set up totally my CE24 I have no string buzz when I play cool on my guitar, or when it's not fretted. But if I attack, the E and D strings buzz (black sabbath, paranoid). Is it because I do it wrong or all the guitars buzz when you play harder ? Using strings like NYXL can change something ? nota : I don't hear the buzz in the ampli, only with volume to zéro.
