I bought a new marshall code 25 and plugged in my guitar to test if everything works fine. But when I touch a string the Amp makes a quite but annoying and strange "crack" sound, but only when I touch it. That happens when I even not play the string, it's enough to put your finger slow on the string. Also the Amp rustle when I'm playing but not when I'm not playing, is that normal??
Come somebody tell me please if they have the same problem or if that's normal?!
