Hi and sorry for my english...
I have a M1 pickup on my Aria AD-80.
I also have the Para Di.
well...when I play my guitar, I feel strange resonances (like two pichtes, buzz...) wich vanish, but not entirely, when I tighten more the clamps!
I do not think that is the solution.
I applied thin cork pads between the clamps and guitar, but nothing to do...the same problem!
the guitar could be the cause?
please help me,
