As above. I got MM Stingray 4 with piezo, few years old. I like it much but one thing is annoying me. G string buzzes badly, especially when I hit her hard. Piezo Stingrays have different bridges, there are piezo saddles under strings, I dont know if that is what causes buzzing or something else. Good thing that its most audible when I play unplagged, hard to hear when plugged but this thing makes me pissed. Anybody had similar problem???
