Hi Bill,

Is this the T-Class in the video you sent me the link to?

If so, and the buzz gets worse when you touch the strings or bridge, it suggests the coaxial wire's braided shield may not be properly contacting the metal of the fixed bridge plate. The rectangular pad on the recessed circuit board is not connected to the metal of the bridge so the wire must be sandwiched between the plate and the body wood. Because the body of each sensor is ground, string ground for the X-Bridge is established by that wire being held down by the bridge.

Please reply if that doesn't help the situation.
