JP7 ernie ball piezo buzzing

[shadyru]

I just bought a used JP7 and is freaking awesome except for this certain weird buzzing sound that pops up here and there in piezo mode(the sound sound like as if the signal is coming in 2 high type of sound). What do I do? I just put a hunk of money and can't return it Can someone help me in a step by step what I should be looking for and testing? Any thoughts?
